Ordinarily, all of the mantissa bits are used to express significant figures, in addition to a leading 1, which is implied and, thereforeas a result, left out. Floats, consequently, have 24 significant bits of precision; doubles have 53 significant bits of precision. Such numbers are called normalized numbers. All-floating point numbers are limited in this sense because they have fixed precision.
