Standard

FORTRAN 77 and later

Class

Elemental function

Syntax

result = cos(x)

Arguments

x - The type shall be real or complex.

Return value

The return value is of the same type and kind as x. The real part of the result is in radians. If x is of the type real , the return value lies in the range~~(削除) -1 (削除ここまで)(削除) \leq (削除ここまで)(削除) \cos (削除ここまで)(削除) (x) (削除ここまで)(削除) \leq (削除ここまで)(削除) 1. (削除ここまで)~~(追記) $-1 \leq \cos (x) \leq 1$ (追記ここまで)(追記) . (追記ここまで)

Example

program test_cos
 real :: x = 0.0
 x = cos(x)
end program test_cos
