[Definition:] The double datatype is patterned after the IEEE double-precision 64-bit floating point type [IEEE 754-1985]. The basic value space of double consists of the values m 2^e, where m is an integer whose absolute value is less than 2^53, and e is an integer between -1075 and 970, inclusive. ... It seems to me that "e" should be an integer between -1074 and 971, inclusive.
