FAST way to convert any number to a *char type string

BungoMan85 · 2003-04-02T03:13:57

whats the FASTEST way to convert all numbers (int, float, double, ect) to a *char string? i know similar topics have been addressed but im really curious as to the fastest (as in most efficient in all regards) way of doing it (well in all regards except the actual length of the code, im more concerned about memory usage and processing time Bungo!

Sprintf is like the C i/o functions. You can use it wherever, even though I think it was made for dos. The MSDN has some stuff about it... I can't really explain it.

Actually, it was originally written for UNIX. As was almost everything related to C in the 1970's

Yes you can use it anywhere, as all compilers worth anything will have implementations of the standard C library.

With my loader calling getline and then using atof was about 10x slower than simply usin ifstream >> iVariable... strange.

I like boost::format.

But you''re asking about speed. I have no idea how fast it is. Converting numbers to strings isn''t really high on my list of time critical things to optimize. (things like rendering usually require more thought)

I''m hip because I say "M$" instead of "MS".

itoa, atoi, ftoa, atof, and numerous other functions are probably faster than sprintf, because they are more specific to your needed conversion. Not that either is slow enough to really bother optimizing...
