floating-point arithmetic, the significand is a component of a finite floating-point number
containing its significant digits.
Generally speaking, the significand can be thought of as an
integer, as a fraction, or as some other fixed-point form by
choosing an appropriate exponent offset (that is, an appropriate bias).
What's more, a decimal or subnormal binary significand
may also contain leading zeros.
