-no-IPF-fltacc
Windows:  /QIPF-fltacc
/QIPF-fltacc-

Arguments

None

Default

-no-IPF-fltacc or
/QIPF-fltacc-		 Optimizations are enabled that affect floating-point accuracy.

Description

This option disables optimizations that affect floating-point accuracy.

If the default setting is used, the compiler may apply optimizations that reduce floating-point accuracy.

You can use this option or option fltconsistency to improve floating-point accuracy, but at the cost of disabling some optimizations.

Alternate Options

Linux: -IPF_fltacc
Windows: /QIPF_fltacc
