Syntax:
The /math_library option specifies whether argument checking of math routines is done on ia32 systems. This option is ignored on ia64 systems.
In the visual development environment, specify the Math Library in the Optimizations (or Code Generation) Compiler Option Category. The /math_library options are: /math_library:fast and /math_library:check:
On ia32 systems, /math_library:fast improves performance by not checking the arguments to the math routines. Using /math_library:fast makes tracing the cause of unexpected exceptional values results difficult. Specifying /math_library:fast does not change the accuracy of calculated floating-point numbers.
On ia32 systems, /math_library:check validates the arguments to and results from calls to the Fortran math routines. This provides slower run-time performance than /math_library:fast, but with earlier detection of exceptional values. This is the default on ia32 systems.
