- Promotes interoperability among programming languages
|
|
- 32 bit

|
- Leftmost bit is a sign bit (0=+ve 1=-ve)
|
|
- 8 bit exponent (127 bit unsigned binary number)
|
|
- 23 bit mantissa _without_ the 1 infront of the binary point

### Scientific Notation
|
|
13.5 = 1101.1 = 1.1011x2 ^3
|
|
2.75 = 10110.11 = 1.011011x2 ^4
|
|
0.125 = 0.001 = 1x2 ^-3
|
|
|
