Result Type and Attributes

• Real.
• Case (i): If A is of type integer or real and KIND is present, the kind type parameter is that specified by KIND. If A is of type integer or real and KIND is not present, the kind type parameter is the kind type parameter of the default real type.
• Case (ii): If A is of type complex and KIND is present, the kind type parameter is that specified by KIND. If A is of type complex and KIND is not present, the kind type parameter is the kind type parameter of A.

Result Value

• Case (i): If A is of type integer or real, the result is equal to a kind-dependent approximation to A.
• Case (ii): If A is of type complex, the result is equal to a kind-dependent approximation to the real part of A.

Examples

REAL (-3) has the value -3.0. REAL ((3.2, 2.1)) has the value 3.2.
