I've written a code in C that performs several computations at various time steps. I want to save the results for each time step in a file. So if anybody can help me, how to change a float type number (the time value ex. 10.25) into a string so i can strcpy it into the file name.<br>ThankYou

I assume there is an ftoa command, just like there is an itoa, atoi, ltoa, atol commands.
