Summary
The optimized PIC32 Math Library is packaged within the
MPLAB C Compiler for PIC32 MCUs. The floating-point math
library provided with the compiler has been significantly
optimized to take full advantage of the PIC32 MCU
instruction set. Single-precision and double precision
math library functions are now available, giving users a
choice between double- and single-precision operations.
The library provides the greatest benefit for the more
complex operations offering a greater than 5x performance
improvement over the previous versions of library for many
operations.
