EuiRange step property does not support decimals

[nreese]

The following throws an error but should be valid

<EuiRange
  min={.00}
  max={1.00}
  step={.05}
  showLabels
  showInput
  showRange
/>

It does support decimals. We'll have to dig deeper into the logic/math that's doing the sequence calculations. Maybe it's that floating decimal issue that was raised.

Yep, this is the second failing functional test in the eui-update-in-kibana PR. I'll have an EUI fix for it tomorrow morning and is the last thing to get kibana updated.
