ACOSD (The GNU Fortran Compiler) (original) (raw)


8.7 ACOSD — Arccosine function, degrees

Synopsis:

RESULT = ACOSD(X)

Description:

ACOSD(X) computes the arccosine of X in degrees (inverse ofCOSD(X)).

Class:

Elemental function

Arguments:

X The type shall either be REAL with a magnitude that is less than or equal to one.

Return value:

The return value is of the same type and kind as X. The real part of the result is in degrees and lies in the range_0 \leq \Re \acos(x) \leq 180_.

Example:

program test_acosd real(8) :: x = 0.866_8 x = acosd(x) end program test_acosd

Specific names:
