-Internally, a number is represented in 64-bit format [IEEE-754](http://en.wikipedia.org/wiki/IEEE_754-1985), so there are exactly 64 bits to store a number: 52 of them are used to store the digits, 11 of them store the position of the decimal point (they are zero for integer numbers), and 1 bit is for the sign.

 If a number is too big, it would overflow the 64-bit storage, potentially giving an infinity:
