The OMTRIG library is a collection of trigonometric functions based on the C math library. It augments the OMFLOAT library. You can use the functions in this library to write OmniMark applications that can calculate trigonometric functions.
To use OMTRIG, you must import both it and OMFLOAT into your program using statements like this:
import "omfloat.xmd" unprefixed import "omtrig.xmd" unprefixed
