### Representation of numbers - Swarthmore College.

For a fraction with 15 bits of resolution this gives a range of approximately 0.99997 to 3.05E-5. Note that this representationis easily extended to represent all positive numbers by having the digits to the left of the decimal point represent the integer part, and the digits to the right representing the fractional part. Thus. 6.625 10 = 110.101 2.
