Floating-point types

Floating-point types are a little more complicated than whole-number types.

I found the following definition of floating-point in the Free On-Line Dictionary of Computing at this URL:

"A number representation consisting of a mantissa, M, an exponent, E, and an (assumed) radix (or "base") . The number represented is M*R^E where R is the radix - usually ten but sometimes 2."
