FIXEDFormats a number with a fixed number of decimal places.
FIXED(number, [number_of_places], [suppress_separator])
number – The number to format.
number_of_places – [ OPTIONAL ] – The number of decimal places to display in the result.
If number has fewer than number_of_places significant digits, zeros will be appended. If it has greater than number_of_places significant digits, number will be rounded to the correct number_of_places rather than truncated.
suppress_separator – [ OPTIONAL – 0 by default ] – Whether or not to suppress the thousands separator used in some locales (e.g. 1,000 becomes 1000). Separators will be present if this value is 0 or omitted, and absent otherwise.
