number Function (Windows CE 5.0)
Converts the argument to a number.
numbernumber(object?)
Parameters
- object
[optional] An object to be converted to a number.
Return Values
Converts its argument to a number as shown in the following list:
- A string that consists of optional white space followed by an optional minus sign followed by a number followed by white space is converted to the IEEE 754 number that is nearest (according to the IEEE 754 round-to-nearest rule) to the mathematical value represented by the string; any other string is converted to NaN.
- Boolean True is converted to 1; Boolean False is converted to 0.
- A node set is first converted to a string and then converted in the same way as a string argument.
- An object of a type other than the four basic types (node-set, Boolean, number, or string) is converted to a number in a way that is dependent on that type.
If the argument is omitted, it defaults to a node set with the context node as its only member.
**Note **The number function should not be used for conversion of numeric data occurring in an element in an XML document unless the element is of a type that represents numeric data in a language-neutral format (that would typically be transformed into a language-specific format for presentation to a user). In addition, the number function cannot be used unless the language-neutral format used by the element is consistent with the XML Path Language (XPath) syntax for a number.
Requirements
None.
