Fixed number precision when draggableRange=true

When there was set options.precision>0 (non-zero fraction part)
and moved a range there was a issue with number rounding on both
ends of selected range. Sometimes numbers had small value at far fraction.

It can be reproduced with live demo by setting, for example:
  minValue: 3.6,
  maxValue: 5.8
  floor: 0,
  ceil: 10
  step: 0.1,
  precision: 1,
  draggableRange: true

It's possible to produce value, e.g: 6.2999999999... but used precision
expects to see rounded value: 6.3.
