Class
result = AINT(A [, KIND])
AINT(A [, KIND]) truncates its argument to a whole number.
A - the type of the argument shall be REAL. KIND - (optional) an INTEGER initialization expression indicating the kind parameter of the result.
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 the magnitude of X is less than one, aint(x) returns zero. If the magnitude is equal to or greater than one then it returns the largest whole number that does not exceed its magnitude. The sign is the same as the sign of X.
Sample program:
program demo_aint real(4) x4 real(8) x8 x4 = 1.234E0_4 x8 = 4.321_8 print *, aint(x4), dint(x8) x8 = aint(x4,8) end program demo_aint
