Language Reference

INT(A, KIND)

Convert to integer type.

A

must be of type integer, real, or complex.

KIND (optional)

must be a scalar integer initialization expression.

Class

Elemental function

Result Type and Attributes

• Integer.
• If KIND is present, the kind type parameter is that specified by KIND; otherwise, the kind type parameter is that of the default integer type.

Result Value

• Case (i): If A is of type integer, INT (A) = A.
• Case (ii): If A is of type real, there are two cases: if |A| < 1, INT (A) has the value 0; if |A| >= 1, INT (A) is the integer whose magnitude is the largest integer that does not exceed the magnitude of A and whose sign is the same as the sign of A.
• Case (iii): If A is of type complex, INT (A) is the value obtained by applying the case (ii) rule to the real part of A.
• The result is undefined if it cannot be represented in the specified integer type.

Examples

INT (-3.7) has the value -3.
