What Language Environment math services does

Language Environment math services provide standard math computations and can be called from Language Environment-conforming languages or from Language Environment-conforming assembler routines.

You can invoke Language Environment math services by using the call interface or by using the C, COBOL, Fortran, or PL/I built-in math functions specific to the HLL used in your application. For example, your COBOL program can continue to use the built-in SIN function without having to be recoded to use the CEESxSIN call interface.

Language Environment provides several bit manipulation routines to support existing Fortran functions. The scalar versions of Language Environment bit manipulation routines can be called from programs written in any language. For more information on using bit manipulation routines, see z/OS Language Environment Programming Reference.
