        simcalc computes floating point numbers and polynomials over
        floating point numbers with a precision of DIGITS digits. 
        By default, DIGITS = 37. In order to adjust this precision 
        to s digits, please type "DIGITS = s", where s is single 
        precision number.
        The variable OUTPUTDIG determines the output format. If
        OUTPUTDIG = 0, the output is in scientific notation.
        If OUTPUTDIG > 0, the output is in fixpoint notation with
        OUTPUTDIG digits. By default, OUTPUTDIG = 0. In order to 
        adjust this precision to s digits, please type "OUTPUTDIG = s", 
        where s is a nonnegative single precision number < DIGITS.

        The following functions are available for floating point numbers:
