Declarations of the integer-exponent power functions, with names prefixed with an
underscore, appeared in the HP-UX 11i v1.5 math.h header, though were not
documented in the manpages. The underscore-prefix names are retained in the HP-UX
11i v1.6 math.h header (and the entry points are still in libm.a).
Performance
There is no impact to performance.
Obsolescence
Not applicable.
Documentation
The new rsqrt (3M) manpage describes the reciprocal square root functions.
The pow (3M) manpage is augmented to cover the integer-exponent power functions.
The new functions are mentioned in the math library white paper, which is updated for
HP-UX 11i v1.6 and can be found at:
