Enables the compiler to replace calls to transcendental functions with faster but less precise implementations.
IA-32, IntelĀ® 64, IA-64 architectures
Linux and Mac OS X: |
-fast-transcendentals -no-fast-transcendentals |
Windows: |
/Qfast-transcendentals /Qfast-transcendentals- |
-fast-transcendentals or /Qfast-transcendentals |
The default depends on the setting of -fp-model (Linux and Mac OS X) or /fp (Windows). |
This option enables the compiler to replace calls to transcendental functions with implementations that may be faster but less precise.
It tells the compiler to perform certain optimizations on transcendental functions, such as replacing individual calls to sine in a loop with a single call to a less precise vectorized sine library routine.
This option has an effect only when specified with one of the following options:
Windows* OS: /fp:except or /fp:precise
Linux* OS and Mac OS* X: -fp-model except or -fp-model precise
You cannot use this option with option -fp-model strict (Linux and Mac OS X) or /fp:strict (Windows).
