FIX: Incorrect Floating-Point Calculations with /Ox and /Op

MORE INFORMATION

FORTRAN PowerStation, version 1.0, can be differentiated from the maintenance release, version 1.0a, by invoking the linker. Typing link32 | more from the \F32\BIN directory will show version 2.8 for FORTRAN PowerStation, version 1.0, and will show version 1.0f for the maintenance release, version 1.0a.

The following sample program can be used to demonstrate this problem. The correct result is:

Sample Code

C compile options required: /Oxp

   n1 = 1024
   n2 = 512
   c = (1./n1)+(1./n2)
   write (*,*) c
   write (*,*) (1./n1)+(1./n2)
   end
