prec-sqrt, Qprec-sqrt
Improves precision of square root implementations. This feature is only available for ifort.
Syntax
Linux: |
-prec-sqrt -no-prec-sqrt |
macOS: |
-prec-sqrt -no-prec-sqrt |
Windows: |
/Qprec-sqrt /Qprec-sqrt- |
Arguments
None
Default
-no-prec-sqrt |
The compiler uses a faster but less precise implementation of square root. However, the default is -prec-sqrt or /Qprec-sqrt if any of the following options are specified: /Od, /fltconsistency, or /Qprec on Windows* systems; -O0, -fltconsistency, or -mp1 on Linux* and macOS systems. |
Description
This option improves precision of square root implementations. It has a slight impact on speed.
This option inhibits any optimizations that can adversely affect the precision of a square root computation. The result is fully precise square root implementations, with some loss of performance.
