Language Environment math services provide standard math computations. You can call them from Language Environment-conforming languages or from assembler routines by using the call interface , or the syntax specific to the HLL of your application.

Math services do not depend on enclave-level resources. You can invoke them from any thread.

If your application uses extended-precision arithmetic and runs on a 370-mode machine under VM, you must specify the TRAP(ON) runtime option (the default) and add the CMSLIB TXTLIB with the GLOBAL TXTLIB command.
