DESCRIPTION

anint(a [, kind]) rounds its argument to the nearest whole number.

ARGUMENTS

A	- 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 A is greater than zero, anint(a) returns aint(x + 0.5). If A is less than or equal to zero then it returns aint(x - 0.5).

EXAMPLE

Sample program:

    program demo_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 demo_anint
