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:

• 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.
