In a previous article, michaelv@iastate.edu (Michael L. VanLoon) says:
>On what OS/processor?
FreeBSD-1.0 on a 486/33
To make a point on libm speed, the following program:
#include <math.h>
main()
{
double x, y;
for (x = 0; x < 10000; x += 1)
y = sqrt(x);
}
with libfpu:
[chris@mercury]~/work> /usr/bin/time stst
0.21 real 0.05 user 0.04 sys
and with libm:
[chris@mercury]~/work> /usr/bin/time sqtst
3.19 real 3.13 user 0.00 sys
Big difference.
