remove "parseInt" and speed up some div

[roviury]

remove "parseInt": parseInt(x,10) = (x-0) but (x-0) is faster

the lines is the problem refer to... 1048:

(parseInt( value ) + == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"); (( value -0 ) + == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")");

1267:

return elem[0] && parseInt( jQuery.curCSS(elem[0], prop, true), 10 ) return elem[0] && ( jQuery.curCSS(elem[0], prop, true)-0 )

speed up some div: x/100 = x * 1/100 = x * 0.01 but *0.01 faster than /100 (in most browser can speed up, even if not, it must not speed down) ps.why is some div? the dividend must be constant!

1052: (parseFloat( elem.filter.match(/opacity=([^{)]*)/)[1] ) / 100) + : (parseFloat( elem.filter.match(/opacity=([})]*)/)[1] ) * 0.01) + :

I don't see this code in jQuery core anymore, so I'll it was fixed or rewritten.
