Important Notice
The pages on this site contain documentation for very old MS-DOS software,

If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.

─────Absolute Value and Sign Transfer───────────────────────────────────────
ABS, IABS, DABS, CABS, and CDABS return the absolute value of their
arguments. For a complex number, the absolute value equals
(real**2 + imag**2)**(1/2)
For two arguments (genA, genB), the intrinsic functions SIGN, ISIGN,
and DSIGN return |genA| if genB is greater than or equal to zero,
and -|genA| if genB is less than zero.
