DESCRIPTION
The pow() function returns x
y
.
powf() is a float version of pow(); it takes float arguments and returns a float
result.
Integrity Server Only
powl() is a long double version of pow(); it takes long double arguments and returns a
long double result.
poww() is an extended version of pow(); it takes extended arguments and returns an extended
result.
powq() is equivalent to powl() on HP-UX systems.
The pown() function returns x
y
.
pownf() is a float version of pown(); it takes a float first argument and returns a
float result.
pownl() is a long double version of pown(); it takes a long double first argument and
returns a long double result.
pownw() is an extended version of pown(); it takes an extended first argument and returns an
extended result.
pownq() is equivalent to pownl() on HP-UX systems.
The powlln() function returns x
y
.
powllnf() is a float version of powlln(); it takes a float first argument and returns a float
result.
powllnl() is a long double version of powlln(); it takes a long double first argument and
returns a long double result.
powllnw() is an extended version of powlln(); it takes an extended first argument and returns
an extended result.
powllnq() is equivalent to powllnl() on HP-UX systems.
