Description

Add a simple function to cast value to number, either as jQuery.num( <value>[, <onFalse=0>[, <type=float|int>]] ) or as separate functions jQuery.int( <value>[, <onFalse=0>] ) and jQuery.float( <value>[, <onFalse=0>] ).

Bellow follows example functions:

    function int(value, onFalse)
    {
        // Checks if value is int, if not onFalse or 0 is returned
        value = parseInt( value );
        return isNaN( value ) ? ( onFalse !== undefined ? onFalse : 0 ) : value;
    }
    function float(value, onFalse)
    {
        // Checks if value is float, if not onFalse or 0 is returned
        value = parseFloat( value );
        return isNaN( value ) ? ( onFalse !== undefined ? onFalse : 0 ) : value;
    }

"onFalse" should have been "onNaN"

Feels unnecessary to me. It's one line to do in pure JS. Why clutter the source with methods for it?

Sounds like a feature that could be easily handled by a non jQuery method. It doesn't really relate to any of the things jQuery is really good at other than its in Javascript.

This is not appropriate for jQuery core.

This should be reconsidered. It may only be one line of pure JS, but I'd prefer to push that one line up into jQuery rather than having to litter my code with 100's of lines like this:

parseInt($('selector').val(), 10);

I fail to see how

jQuery.num( $("selector").val(), 0, "int" );

is a preferable form of "litter."
