The Pentium (along with every other major microprocessor) uses the
IEEE 754 standard to represent floating point numbers. A floating-
point number stores a real number as sign*1.XXX*2^YYY, i.e. one
plus a fraction, raised to a power of two, along with the sign.
The XXX part is the mantissa and the YYY part is the exponent.

The IEEE standard defines a single-precision number to have a
23-bit mantissa. This provides 24-bit precision (counting the
leading one) and is equal to approximately 7 decimal digits.
