The relevant ECMAScript implementations support only one numeric data type, 
Number, which is an implementation of IEEE-754 double-precision floating-
point values.  Each such value requires 64 bits of storage (1 sign bit, 11 
exponent bits, and 52 mantissa bits), or _8_ bytes whereas each byte 
consists of 8 bits.
