Description. Convert to integer type. +! Class. Elemental function. +! Arguments. +! A shall be of type integer, real, or complex, +! or a boz-literal-constant . +! KIND (optional) shall be a scalar integer initialization expression. +! +! Result Characteristics. Integer. If KIND is present, the kind type +! parameter is that specified by the value of KIND; otherwise, the +! kind type parameter is that of default integer type. +! +! Result Value. +! +! Case (1): If A is of type integer, INT (A) = A. +! +! Case (2): If A is of type real, there are two cases: +! (a) if |A| < 1, INT (A) has the value 0 +! (b) if |A| .ge. 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 (3): If A is of type complex, INT(A) = INT(REAL(A, KIND(A))). +! +! Case (4): If A is a boz-literal-constant, it is treated as if it were +! an int-literal-constant with a kind-param that specifies the +! representation method with the largest decimal exponent range +! supported by the processor. +! +! Example. INT (3.7) has the value 3. +! +module mykinds + integer, parameter :: ik1 = selected_int_kind(2) + integer, parameter :: ik2 = selected_int_kind(4) + integer, parameter :: ik4 = selected_int_kind(9) + integer, parameter :: ik8 = selected_int_kind(18) + integer, parameter :: sp = selected_real_kind(6,30) + integer, parameter :: dp = selected_real_kind(15,300) + integer, parameter :: ck = kind('a') +end module mykinds + +program test_int + + use mykinds + + integer(ik1) i1 + integer(ik2) i2 + integer(ik4) i4 + integer(ik8) i8 + real(sp) r4 + real(dp) r8 + complex(sp) c4 + complex(dp) c8 + ! + !
