NAME
    IEEEDPCeil -- compute Ceil function of IEEE double precision number

SYNOPSIS
      x   = IEEEDPCeil(  y  );
    d0/d1              d0/d1

    double  x,y;

FUNCTION
    Calculate the least integer greater than or equal to x and return it.
    This value may have more than 32 bits of significance.
    This identity is true.  Ceil(x) = -Floor(-x).

INPUTS
    y -- IEEE double precision floating point value

RESULT
    x -- IEEE double precision floating point value
