18 bits to represent a little more than 5 decimals

Approximately 3.3 bits are required to represent a little more

than 5 decimal digits

ob/c 2^3.3=10

since binary multiplication table is so simple, multiplication can

be implemented in a computer fairly easily.

Shifting a binary number one position to the left has the e%ect of

doubling its value

In general, shifting a number in any base left one digit multiplies

its value by the base, and, conversely, shifting a number right

one digit divides its value by the base

Each hexadecimal number represents exactly 4 binary bits

Decimal speci+cally implies base 10

oTherefore use number point (binary point, hexadecimal

point, etc)

oSometimes called radix point

oBase 3 number point called ternary point

When converting numbers that contain both integers and

fractions, both parts must me converted separately
