The abs function computes the absolute value of an integer j. If the result cannot be represented, the behavior is undefined.
| The abs function is both built-in and supplied as a library function. Usually the built-in function is used, and the appropriate instructions will be generated. If the address of the abs function is taken, then the address is the address of the library function. |
| On the M1750, in the special case where j is -32768, fixed point overflow will be detected by the 1750 and if the corresponding interrupt is enabled the signal SIGFIXED_OVERFLOW will be raised. |
| The standard behavior may be modified in the run-time system file crt0.s. |
