The function to convert an array of bytes into a number. The result can be double or long values.
The numbers are stored in the IEEE 754 format. A number is considered long if the difference between the whole
number and its integer part is less than {@link SasFileConstants#EPSILON}.

@param mass the number represented by an array of bytes.
@return number of a long or double type.
