UA Class
+ + + + +YUI user agent detection. +Do not fork for a browser if it can be avoided. Use feature detection when +you can. Use the user agent as a last resort. For all fields listed +as @type float, UA stores a version number for the browser engine, +0 otherwise. This value may or may not map to the version number of +the browser using the engine. The value is presented as a float so +that it can easily be used for boolean evaluation as well as for +looking for a particular range of versions. Because of this, +some of the granularity of the version info may be lost. The fields that +are @type string default to null. The API docs list the values that +these fields can have.

Performs a simple comparison between two version numbers, accounting for +standard versioning logic such as the fact that "535.8" is a lower version than +"535.24", even though a simple numerical comparison would indicate that it's +greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are +considered equivalent.
+ +Returns -1 if version a is lower than version b, 0 if they're equivalent, +1 if a is higher than b.
+ +Versions may be numbers or strings containing numbers and dots. For example,
+both 535 and "535.8.10" are acceptable. A version string containing
+non-numeric characters, like "535.8.beta", may produce unexpected results.
