What every computer scientist should know about floating point.
Everything you want to know is on the wikipedia page for IEEE-754: http://en.wikipedia.org/wiki/IEEE_754-2008.
The mantissa is 23 bits in a float
, but the stored value is normalized, meaning that there's an implied leading 1 followed by a decimal point. This takes it to 24 effective bits.
