Why not. I'll post my answer just since it came out faster than
sprintf. Well, when I pass in a buffer, rather than allocating it in
the function. Don't know about the speed comparison when allocating.
Not that this answers your question...
Yes, it turns out that using log10() is the slow point. Floating point
math must be a lot slower than I thought. I wrote and used this
integer-based log10 function function instead and now my code is about
twice as fast as sprintf(). Yay.
int log10i( unsigned int i )
{
int ret = 0;
while( i )
{
i /= 10;
ret++;
}
return ret;
}
