+IEEE-754
+- 32 and 64 bit numbers
+	- Float and double in java
+	- 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
