I think the range is -2^53 to 2^53 + 1 given by: "A floating-point format is specified by: a base (also called radix) b, which is either 2 (binary) or 10 (decimal) in IEEE 754; a precision p; an exponent range from emin to emax, with emin = 1 − emax for all IEEE 754 formats."

Minor correction: the minimum allowed integer value should be -2^53 + 1.
