Returns the max precision within an Iterator of numbers.
If this is a float, this method returns the number of decimals.
If this is an integer, this method returns a negative number.

@param itr {Arrays.Iterator}
@param noError {Boolean} Optional. Whether throw exception when encountering a
non-numeric value. Default is 'false'.
@return {Number} Integer
@see Number.precision
Returns the max precision within an Iterator of numbers . If this is a float this method returns the number of decimals . If this is an integer this method returns a negative number .
