| Linux and Mac OS: | -prec-sqrt -no-prec-sqrt |
| Windows: | /Qprec-sqrt /Qprec-sqrt- |
None
| OFF | The compiler uses a faster but
less precise implementation of square root.
Note that the default is ON if any of the following options are specified: /Od, /Op, or /Qprec on Windows systems; -O0, -mp (or /fltconsistency), or -mp1 on Linux and Mac OS systems. |
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.
