11.1
The dsPIC33F Math Library is the compiled version of
the math library that is distributed with the highly
optimized, ANSI-compliant dsPIC33F MPLAB C30 C
Compiler (SW006012). It contains advanced single and
double-precision
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.
