Description

Functions that relate to the Floating-Point Arithmetic Unit.

Some Cortex-M processors include optional floating-point arithmetic functionality, with support for single and double-precision arithmetic. The Cortex-M processor with FPU is an implementation of the single-precision and double-precision variant of the Armv7-M Architecture with Floating-Point Extension (FPv5).
