* Decimal and float really belong side-by-side in the tower, rather than one above the other. Neither of them is inherently any more precise or exact than the other.
Except that float is fixed-width (typically 53 bits of precision), while Decimal allows a user-specified, arbitrarily large, precision; so in that sense the two floating-point types aren't on an equal footing.
