INT(A, KIND)

Purpose

Convert to integer type.

Class

Elemental function

Argument type and attributes

A

An INTENT(IN) INTEGER, REAL, COMPLEX, or boz-literal CONSTANT

KIND (optional)

An INTENT(IN) INTEGER scalar. The actual argument corresponding to KIND must be a constant expression.

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.
• Case (iv): If A is a boz-literal constant, it is treated as an integer with a kind-param that specifies the representation method with the largest decimal exponent range supported by the processor. If -qxlf2003=nobozlitargs is specified the boz-literal is treated as a real.
• The result is undefined if it cannot be represented in the specified integer type.
