REAL — Convert to real type#

REAL(A[, KIND])#

REAL(A [, KIND]) converts its argument A to a real type. The REALPART function is provided for compatibility with g77, and its use is strongly discouraged.

Parameters

A – Shall be INTEGER, REAL, or COMPLEX.
KIND – (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

Returns

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

Standard:

Fortran 77 and later, with KIND argument Fortran 90 and later, has GNU extensions

Class:

Elemental function

Syntax:

RESULT = REAL(A [, KIND])
RESULT = REALPART(Z)

Example:

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