Convert binary numbers to decimal numbers

Binary number = 1011 1001
| Binary value | 1 | 0 | 1 | 1 | 1 | 0 | 0 | 1 |
|---|---|---|---|---|---|---|---|---|
| Decimal value | 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
(1 x 128) + (0 x 64) + (1 x 32) + (1 x 16) + (1 x 8) + (0 x 4) + (0 x 2) + (1 x 1) = 185
Another way to convert a binary number into a decimal number is to identify a
- Identify decimal number value for each 1 in the binary number
- Add decimal number values together from left to right
(128)+(32)+(16)+(8)+(1) = 185
