The trigonometry library, omtrig, is a collection of trigonometric functions based on the C math library. It serves as a "wrapper" around a particular math library. You can use the functions in this library to write OmniMark applications that can perform double-precision floating point arithmetic.
The trigonometry function library consists of the following files:
include omtrig.xin) because the file contains the external function declarations, the float type definition, and related macros.
To use these functions, you must include the following code near the top of your program:
; floating point function and constant declarations include "omtrig.xin"
