Methods
isFloat(floatVal) → {Boolean}
Returns if a value is a numeric value, usable as a float number in any calculation. Any number that fulfills isInt, is also considered a valid float, which lies in JS's nature of not differentiating ints and floats by putting them both into a "number"-type. So ints are always floats, but not necessarily the other way round.
Parameters:
| Name | Type | Description |
|---|---|---|
floatVal |
* | the value to check |
Returns:
true if floatVal is usable in a float context

Example

}
