xsd:double
The type xsd:double represents an IEEE double-precision 64-bit floating-point number. The format of xsd:double values is a mantissa (a number which conforms to the type E" or "e" followed by an exponent. The exponent must be an integer. For example, 3E2 represents 3 times 10 to the 2nd power, or 300. The exponent must be an integer.
In addition, the following values are valid: INF (infinity), -INF (negative infinity), and NaN (Not a Number). INF is considered to be greater than all other values, while -INF is less than all other values. The value NaN cannot be compared to any other values, although it equals itself.
