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


8.24 ATAND — Arctangent function, degrees

Synopsis:

Description:

ATAND(X) computes the arctangent of X in degrees (inverse ofTAND — Tangent function, degrees).

Class:

Elemental function

Arguments:

X The type shall be REAL; if Y is present, X shall be REAL.
Y The type and kind type parameter shall be the same as X.

Return value:

The return value is of the same type and kind as X. The result is in degrees and lies in the range_-90 \leq \Re \atand(x) \leq 90_.

Example:

program test_atand real(8) :: x = 2.866_8 x = atand(x) end program test_atand

Specific names:
