NAME
        arnd - ASCII round of the provided floating point string

   SYNOPSIS
        arnd(place, exp, &string[0]);

   FUNCTION
        Accepts an ASCII string representing an FFP floating point
        number, the binary representation of the exponent of said
        floating point number and the number of places to round to.
        A rounding process is initiated, either to the left or right
        of the decimal place and the result placed back at the
        input address defined by &string[0].

   INPUTS
        place - integer representing number of decimal places to round to
        exp - integer representing exponent value of the ASCII string
        &string[0] - address where rounded ASCII string is to be placed
                     (16 bytes)

   RESULT
        &string[0] - rounded ASCII string
