Math APIs

The ILE math bindable APIs can be called either through the intrinsic functions of an ILE high-level language, or from an ILE HLL as a call to the API.

For information about using the math APIs, see the following topics:

Data Types and Limits. Describes the data types used in math bindable APIs, along with special values and limits.
Calling Math Bindable APIs. Describes how to specify required and omissible parameters.
Passing Parameters Using Math Bindable APIs. Describes how parameters are passed.
Message Descriptions. Summarizes messages that can be generated by the math bindable APIs.

The following math bindable APIs are presented in the Math API Descriptions table.
