Description

real(x [, kind]) converts its argument x to a real type.~~(削除) The (削除ここまで)(削除) realpart(x) (削除ここまで)(削除) function is provided for compatibility with (削除ここまで)(削除) g77 (削除ここまで)(削除) , and its use is strongly discouraged. (削除ここまで)~~

Standard

Fortran 77 and later

Class

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:

real(x) is converted to a default real type if x is an integer or real variable.
real(x) is converted to a real type with the kind type parameter of x if x is a complex variable.
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(削除) ), (削除ここまで)(削除)  (削除ここまで)(削除) realpart (削除ここまで)(削除) ( (削除ここまで)(削除) x (削除ここまで))
end program test_real
