------- Comment #17 from pault at gcc dot gnu dot org 2006-10-31 16:21 -------
The fortran version of Uros' #13:
real(8) :: x
real(8) :: t = 0.0
x = 10000000.0
do while (x > 0.0)
t = t + mod (x, 1.7e-8)
x = x - 1.0
end do
print *, t
end
Yields:
$ /irun/bin/gfortran -O2 -march=pentium -mfpmath=387 uros_test.f90

$ time ./a
8.499998368231765E-002
real 0m0.344s
user 0m0.327s
sys 0m0.015s
on a PIV running at 2.5GHz
Changing MOD => MODULO, the user time increases to 0.405s for the
implementation in the second attachment.
