Calculate an arithmetic expression.

The multiply operator calculates the product of two real numbers.  I'm not going to explain how multiplication works; take a class in Elementry School if you need help. 
If the absolute value of the result is greater than 1.70141183e+38 then an OVERLOW ERROR occurs.  If the absolute value of the result is less than 2.93873588e-39 then it silently underflows to zero.  If either multiplicand or multiplier is not numeric, a TYPE MISMATCH ERROR occurs; if either is not a valid expression, SYNTAX ERROR occurs.
The multiply operator has the second-highest fixed priority (the same as divide, but lower than power).  The user of course may over-ride the built-in operator priorities by using parentheses "(" and ")".
Like all operators, the result may be printed, stored in an appropriate variable, or combined with other operators in a larger expression.  In this case, a numeric variable is required for storage.  But if the variable is an integer, the minimum result that can be stored is -32768 and the maximum is +32767; otherwise an ILLEGAL QUANTITY ERROR is generated.
