biggest integer that can be stored in a double

Question

What is the biggest \"no-floating\" integer that can be stored in an IEEE 754 double type without losing precision ?

Answer 1

Wikipedia has this to say in the same context with a link to IEEE 754:

On a typical computer system, a 'double precision' (64-bit) binary floating-point number has a coefficient of 53 bits (one of which is implied), an exponent of 11 bits, and one sign bit.

2^53 is just over 9 * 10^15.
