Name Description
number The Number value to format.
format The formatting to apply to the Number value. A format accepts # or 0 (but not both) as placeholders for decimal values, and only one decimal point is permitted. A null or empty String value has no effect on the Number value. Most other values are treated as literals, but you must escape special characters, such as a dollar sign (for example, \$). Inner quotations must be closed and differ from the surrounding quotations.
roundMode Optional parameter for rounding decimal values when the formatting presents a rounding choice, such as a format of 0.# for the decimal 0.15. The default is HALF_UP, and a null value returns behaves like HALF_UP. Only one of the following values is permitted:
  • UP: Always rounds away from zero (for example, 0.01 to "0.1" and -0.01 to "-0.1"). Increments the preceding digit to a non-zero fraction and never decreases the magnitude of the calculated value.
  • DOWN: Always rounds towards zero (for example, 0.19 to "0.1" and -0.19 to "-0.1"). Never increments the digit before a discarded fraction (which truncates to the preceding digit) and never increases the magnitude of the calculated value.
  • CEILING: Rounds towards positive infinity and behaves like UP if the result is positive (for example, 0.35 to "0.4"). If the result is negative, this mode behaves like DOWN (for example, -0.35 to "-0.3"). This mode never decreases the calculated value.
  • FLOOR: Rounds towards negative infinity and behaves like DOWN if the result is positive (for example, 0.35 to "0.3"). If the result is negative, this mode behaves like UP (for example, -0.35 to "-0.4"). The mode never increases the calculated value.
  • HALF_UP: Default mode, which rounds towards the nearest "neighbor" unless both neighbors are equidistant, in which case, this mode rounds up. For example, 0.35 rounds to "0.4", 0.34 rounds to "0.3", and 0.36 rounds to "0.4". Negative decimals numbers round similarly. For example, -0.35 rounds to "-0.4".
  • HALF_DOWN: Rounds towards the nearest numeric "neighbor" unless both neighbors are equidistant, in which case, this mode rounds down. For example, 0.35 rounds to "0.3", 0.34 rounds to "0.3", and 0.36 rounds to "0.4". Negative decimals numbers round similarly. For example, -0.35 rounds to "-0.3".
  • HALF_EVEN: For decimals that end in a 5 (such as, 1.125 and 1.135), the behavior depends on the number that precedes the 5. HALF_EVEN rounds up when the next-to-last digit before the 5 is an odd number but rounds down when the next-to-last digit is even. For example, 0.225 rounds to "0.22", 0.235 and 0.245 round to "0.24", and 0.255 rounds to "0.26". Negative decimals round similarly, for example, -0.225 to "-0.22". When the last digit is not 5, the setting behaves like HALF_UP. Rounding of monetary values sometimes follows the HALF_EVEN pattern.
