Summary
The PIC24/dsPIC® DSC Math Library is the compiled
version of the math library that is distributed with the highly
optimized, ANSI-compliant MPLAB® C Compiler for PIC24
MCUs and dsPIC DSCs (SW006012). It contains advanced
single and double-precision floating-point arithmetic and
trigonometric functions from the standard C header file
<math.h>. The library delivers small program code size and
data size, reduced cycles and high accuracy.

Summary
The Fixed Point Math library provides mathematical functions
useful in for wide range of applications including Motor
Control, Digital Power Control, Digital Signal Processing
and General purpose real-time control using fractional
data types. The Fixed Point math library includes over
65 general-purpose functions composed of twenty eight
functions supporting Q15 math and thirty seven functions
supporting Q16 math.

The PIC24/dsPIC DSC Math Library is callable from
either MPLAB C Compiler or PIC24/dsPIC DSC Assembly
language
The functions are IEEE 754 compliant, with signed zero,
signed infinity, NaN (Not a Number) and denormal support
and operated in the “round to nearest” mode
Compatible with MPLAB ASM30 and MPLAB LINK30
