Description

real(x [, kind]) converts its argument x to a real type.

Standard

(削除) Fortran 77 and later (削除ここまで)(追記) FORTRAN 77 (追記ここまで)(追記) and later (追記ここまで)

Class

Elemental function

Syntax

• result = real(x [, kind])

Arguments

• x - Shall be integer, real, or complex.
• kind - (Optional) An integer initialization expression indicating the kind parameter of the result.

Return value

These functions return a real variable or array under the following rules:

1. real(x) is converted to a default real type if x is an integer or real variable.

2. real(x) is converted to a real type with the kind type parameter of x if x is a complex variable.

3. real(x, kind) is converted to a real type with kind type parameter kind if x is a complex, integer, or real variable.

Example

program test_real
 complex :: x = (1.0, 2.0)
 print *, real(x), real(x,8)
end program test_real
