******************************************************************************

To enter an expression or equation, simply type it in at the prompt.

Operators have precedence decreasing as indicated:

! factorial (gamma function)

** or ^ power (exponentiation)

* multiply

/ divide

% modulus

// integral divide

+ add

- subtract

= equate (lowest precedence)

Multiple operators of the same precedence level are grouped left to right.

Variables consist of any combination of letters, digits, and underscores (_).

Predefined variables follow:

sign, sign1, sign2, ... - may only be +1 or -1

integer, integer1, ... - may be any integer value

Absolute value notation "|x|" and dual polarity "+/-x" are understood.

******************************************************************************

Constants are double precision floating point values with about

14 decimal digits accuracy.

They can be entered in standard, scientific,

or hexadecimal notation.

Excepting named constants, constants always

start with a decimal digit (0..9) or a period.

Named constants follow:

e or e# - the universal constant e (2.7182818284...)

pi or pi# - the universal constant pi (3.1415926535...)

i or i# - the imaginary unit (square root of -1)

The above constants may also be used anywhere variables are required.

inf - floating point infinity constant

nan - invalid floating point result (not enterable)

The largest value of a constant is +/-1.79769e+308

The smallest value of a constant is +/-2.22507e-308
