A decimal is added if the scale is positive and zeros are prepended as necessary. 4. if scale is negative or adjExp is less than -6 we use scientific notation. If the unscaled value has more than one digit, a decimal as inserted after the first digit, the character 'E' is appended and adjExp is appended.
