Description

cos(x) computes the cosine of x.

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

Example

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