  (*
     RealToFloatString - converts a real with, sigFigs, into a string
                         and returns the result as a string.

  (*
     RealToEngString - converts the value of real to floating-point
                       string form, with sigFigs significant figures.
                       The number is scaled with one to three digits
                       in the whole number part and with an exponent
                       that is a multiple of three.

                         string representation of real rounded to the given
                         place relative to the decimal point.
