printf seems to be fine. If I compile and link this snippet of C
#include <stdio.h>
void cprint_(float *x) {
printf("with printf X = %12.8f\n", *x);
}
into my Fortran code
PROGRAM Minus
implicit none
real :: XP
XP = +1.23
print *, "pos X = ", XP
call cprint(xp)
XP = -1.23
print *, "neg X = ", XP
call cprint(xp)
print *, "zero = ", XP+1.23
END PROGRAM Minus
the output is
pos X = 1.2300000
with printf X = 1.23000002
neg X = 1.23000002
with printf X = -1.23000002
zero = 0.0000000
Ho-hum. Memory allocation? It's not even an array any more, could that still be
an issue?
Won't be able to give you access to that machine before tomorrow.
