Improves floating-point precision and consistency.
- The compiler provides good accuracy and run-time performance at the expense of less consistent floating-point results.
This option improves floating-point consistency. It ensures the out-of-range check of operands of transcendental functions and improves the accuracy of floating-point compares.
This option prevents the compiler from performing optimizations that change NaN comparison semantics and causes all values to be truncated to declared precision before they are used in comparisons. It also causes the compiler to use library routines that give better precision results compared to the X87 transcendental instructions.
This option disables fewer optimizations and has less impact on performance than option
and) or option
