[JScript] In JScript, you can use the structures in the NGWS frameworks, but you cannot define your own.
Double can represent numbers in the range negative 1.79769313486231570E+308 through positive 1.79769313486231570E+308, inclusive. The Double type represents a double precision 64-bit IEEE 754 value. The Common Language Specification (CLS) supports primitive types, including Double.
This class provides some basic coercions:
These widening coercions result in no loss in precision of magnitude. Note that programming languages are free to provide coercions that extend or differ from these.
Double provides methods and fields that deal with PositiveInfinity and NegativeInfinity, and expressions that evaluate to not a number (NaN).
