6.6 Floating-Point Unit (FPU) Coprocessor

The PIC32A FPU Coprocessor includes hardware implementations of the most common floating-point operations for both Single Precision (32-bit) and Double Precision (64-bit) data formats. It is intended to significantly accelerate C compiler floating-point operations when compared to executing software library equivalents and is designed to be compliant with the IEEE 754-2008/2019 floating-point standards. It also includes additional non-IEEE compliant features which may be enabled to handle subnormal values and improve performance.
