Usage context

<number>

Real numbers are specified in one of two ways. When used in a stylesheet, a <number> is defined as follows:

number ::= integer
           | [+-]? [0-9]* "." [0-9]+

This syntax is the same as the definition in CSS (CSS2, section 4.3.1).

When used in an SVG attribute, a <number> is defined differently, to allow numbers with large magnitudes to be specified more concisely:

number ::= integer ([Ee] integer)?
           | [+-]? [0-9]* "." [0-9]+ ([Ee] integer)?

Within the SVG DOM, a <number> is represented as a float, SVGNumber or a SVGAnimatedNumber.
