A data type that 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 x 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. In addition to the basic value space described above, the value space of double also contains the following three special values: positive and negative infinity and not-a-number (NaN).
