It is often necessary to convert decimal to binary. The following pages provide a step by step
example.
In order to convert the decimal number 138 into its
binary equivalent we first...
| 1. | Create a binary weighting table making sure that the
leftmost value is greater than or equal to half the
decimal value to be converted.
So to
convert decimal number 138 we halve it to give 69. The values in the
binary weighting table increase in powers of 2 from 1,2,4,....128. The
position 7 value of 64 is less than 69 so we need all eight columns to
cover 138 decimal.
