Hi,The file .../msp430/msp430/include/math.h is a little odd, when built from the latest mspgcc for GCC 3.2.
It contains a block of math related defines, including these two: #define M_PI 3.14159265358979323846 /* pi */ #define M_SQRT2 1.41421356237309504880 /* sqrt(2) */ then near the end of the file they are defined again, a little differently: #define M_PI 3.141592653589793238462643 #define M_SQRT2 1.4142135623730950488016887 Regards, Steve
