| #fdim.S |
| # |
| # An implementation of the fdim libm function. |
| # |
| # The fdim functions determine the positive difference between their arguments |
| # |
| # x - y if x > y |
| # +0 if x <= y |
| # |
| # |
| # |
| # Prototype: |
| # |
| # double fdim(double x, double y) |
| # |
| |
| # |
| # Algorithm: |
| # |
| |
| #include "fn_macros.h" |
| #define fname FN_PROTOTYPE(fdim) |
