FUNCTION: Lang.float
Lang.float( )
The Lang.float function returns a boolean value that indicates
whether the browser supports floating-point numeration. A true
signifies that floating-point is supported. A false signifies that
it is not supported.
If the browser does not support floating-point arithmetic operations,
then the browser will not recognize the Float Library, nor any
of the member functions. In this case, each member function will return
an invalid.
The Lang.isFloat function can be used to determine if a value can
be converted to a floating-point number using the Lang.parseFloat
function.
This function does not take a parameter.
