dsPIC30F
12.1
The dsPIC30F Math Library is the compiled version of
the math library that is distributed with the highly
optimized, ANSI-compliant dsPIC30F MPLAB
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 12-2 shows the memory usage and performance
of the Math Library. Table 12-3 lists the math functions
that are included.
