6.16 ANINT — Nearest whole number

Description:

ANINT(X [, KIND]) rounds its argument to the nearest whole number.

Standard:

F77 and later

Class:

Elemental function

Syntax:

RESULT = ANINT(X [, KIND])

Arguments:

X	The type of the argument shall be REAL(*).
KIND	(Optional) An INTEGER(*) initialization expression indicating the kind parameter of the result.

Return value:

The return value is of type real with the kind type parameter of the argument if the optional KIND is absent; otherwise, the kind type parameter will be given by KIND. If X is greater than zero, then ANINT(X) returns AINT(X+0.5). If X is less than or equal to zero, then it returns AINT(X-0.5).

Example:

          program test_anint
            real(4) x4
            real(8) x8
            x4 = 1.234E0_4
            x8 = 4.321_8
            print *, anint(x4), dnint(x8)
            x8 = anint(x4,8)
          end program test_anint
