JavaScript, using IEEE 754 Doubles, is accurate for addition,
subtraction, and multiplication of integers if the operands and results
are no greater than 2^53.  Division is as accurate as possible under
those conditions; one may want to use it in conjunction with Math.round
Math.floor or Math.ceil.
