POSIX probably has an appropriate routine that'll do just that. You could also try using sprintf with the appropriate %0.2f (or whatever precision you're looking for). finally (TMTOWTDI), you could use the int keyword to truncate it, which might be more effective. for example, to generate dice rolls:
int( rand 6 ) +1;
