1. A pressurized fluid cylinder provided with a valve accommodating a first withdrawing circuit comprising a first, upstream end communicating with a storage volume of a pressurized fluid cylinder and a second, downstream end configured to connect a consumer of the withdrawn gas, the first withdrawing circuit comprising: a member for regulating the flow rate and/or the pressure of the withdrawn fluid between the upstream end and the downstream end, the valve comprising a member for manually controlling the regulating member, a control member being mounted so as to move relative to the body of the valve and cooperating with the regulating member to control the flow rate and/or pressure of fluid allowed to circulate from the upstream end to the downstream end depending on the position of the control member with respect to the body, the valve comprising an electronic device configured to indicate data relating to the fluid content in a cylinder connected to the valve, the electronic device acquiring, storing and processing data and at least one data display connected to the member for acquiring, storing and processing data, the valve comprising a sensor for sensing the position of the member for manually controlling the regulating member, the position sensor acquiring, storing and processing data in order to transmit to a latter a signal indicative of the fluid flow rate and/or pressure set by the regulating member, wherein after the cylinder has been filled and before first withdrawal of fluid, the electronic device acquiring, storing and processing data is configured to cause a fixed information item relating to a given fixed fluid content in the cylinder to be displayed on the display until the position sensor transmits a signal indicative of a non-zero flow rate and/or pressure of fluid withdrawn for a given time and/or until the position sensor transmits a signal indicative of a given quantity of fluid withdrawn, said information item relating to a given fixed fluid content in the cylinder comprising one of the elements selected from the group consisting of: an alphanumeric symbol, a pictorial symbol, a fixed pressure value, a fixed fluid quantity value, the term “full” or “plein”, and the symbol “100%”, and wherein the electronic device acquiring, storing and processing data is configured to determine the quantity of fluid withdrawn on receiving a signal from the sensor for sensing the position of the control member that is indicative of the selection of a non-zero withdrawn fluid flow rate and/or pressure and to cause the removal or modification of the display on the display of the information item relating to a given fixed fluid content in the cylinder when this remaining quantity or remaining pressure determined is equal to a value of between 75% and 99% of the quantity of the fluid contained in the cylinder after it has been filled and/or to cause the removal or modification of the display on the display of the information item relating to a given fixed fluid content in the cylinder in response to the reception of said signal from the sensor for sensing the position of the control member that is indicative of the selection of a non-zero withdrawn fluid flow rate and/or pressure for a time of between 0.1 second and 30 seconds. 2. The cylinder of claim 1, wherein the electronic device acquiring, storing and processing data is configured to detect filling of the cylinder via the reception of an external filling signal and/or via the reception of a signal of an increase in the pressure measured in the cylinder above a given filling threshold. 3. The cylinder of claim 1, wherein the electronic device acquiring, storing and processing data is configured to determine the quantity of fluid withdrawn on receiving a signal from the sensor for sensing the position of the control member that is indicative of the selection of a non-zero withdrawn fluid flow rate and/or pressure and to cause the removal or the modification of the display on the display of the information item relating to a given fixed fluid content in the cylinder when this withdrawn quantity exceeds a volume of between five and one hundred liters of fluid. 4. The cylinder of claim 1, further comprising a pressure sensor for measuring the pressure in the cylinder, the pressure sensor being connected to the electronic device acquiring, storing and processing data in order to transmit to the latter a signal indicative of the fluid pressure measured, the member for acquiring, storing and processing data being configured to determine the variation in pressure or quantity of fluid in the cylinder from this signal of pressure P measured and, in response, to suppress or modify the display on the display of the information item relating to a given fixed fluid content in the cylinder when the determined quantity of fluid withdrawn exceeds a given initial withdrawing threshold. 5. The cylinder of claim 4, wherein the initial withdrawing threshold is between 0.5% and 10% of the initial quantity of gas. 6. The cylinder of claim 1, wherein the electronic device acquiring, storing and processing data is configured to receive both the signal of pressure measured by the pressure sensor and the flow rate and/or pressure signal supplied by the position sensor and to determine an information item relating to autonomy, pressure or quantity of remaining fluid from these two signals. 7. The cylinder of claim 6, wherein the autonomy of remaining fluid is determined by determining, from the initial pressure measured, the theoretical decrease over time in pressure or the quantity of gas generated by the withdrawing flow rate and/or pressure set by the regulating member and/or measured by the pressure sensor. 8. The cylinder of claim 1, wherein the theoretical value relating to the autonomy or content of fluid remaining in the cylinder is expressed in time remaining by dividing the initial pressure measured by the pressure sensor by the theoretical variation in pressure set by the regulating member, by a formula of the type: Time remaining=Initial pressure/variation in pressure set the quantity being estimated via the perfect gas equation (PV=nRT) or real gas equation (PV=ZnRT), where P is the pressure measured, V the known volume of the cylinder, n the quantity, R the perfect gas constant and T the temperature measured or approximated to the ambient temperature measured, Z the compressibility factor known from a table or calculation. 9. The cylinder of claim 1, wherein the member for manually controlling the regulating member is movable into a position known as the “closed” position corresponding to closure of the first withdrawing circuit. 10. The cylinder as of claim 9, wherein the valve further comprises a second withdrawing circuit which bypasses the flow rate and/or pressure regulating member of the first withdrawing circuit, and in that, when the manual control member is in its closed position and the variation in the signal indicative of the fluid pressure within a cylinder is greater than a given variation threshold, the electronic device acquiring, storing and processing data is configured to detect withdrawal of fluid via the second withdrawing circuit or a leak of fluid and cause an information item relating to withdrawal via the second withdrawing circuit and/or relating to a leak to be displayed on the display.
