PIC24H
11.1
The PIC24H Math Library is the compiled version of the
math library that is distributed with the highly optimized,
ANSI-compliant PIC24H MPLAB C30 C Compiler
(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.
Features
• The math library is callable from either MPLAB
• The functions are IEEE-754 compliant, with
• Compatible with MPLAB ASM30 and MPLAB
Table 11-2 shows the memory usage and performance
of the Math Library. Table 11-3 lists the math functions
that are included.
