slider with two handles: When stepping < 1/4 of realMaxValue ->wrong steps created

[nettoyeur]

ui.slider.js, r4730

When minValue=0 and stepping is smaller then 1/4 of maxvalue, it fails to create the proper steps (rounding error?)

how to reproduce: Create slider with two handles.

minvalue:0
maxvalue:1000
stepping:250

->everything ok, steps of 250 are taken

Now try smaller stepping:

minvalue:0
maxvalue:1000
stepping:200

->first step with left slider is 196.8085106382979, second step is 398.93617021276594, third step is 595.7446808510638, fourth step is 797.8723404255319, fifth step is 1000. (expected: 200,400,600,800,1000)

This also occurs in single-handle sliders.

Also, I could really use a fix for this issue ASAP. I need to use 1.5b to be able to use a slider with multiple handles, but using 1.5b also breaks my sliders with this bug.

This is because .value() calculates itself from the position of the element instead of the current position on the stepping

Round value() if stepping

Please apply the patch. tests are passing
