FormatNumber

FormatNumber(number, width, precision, thousandSeparator): String

Formats a numeric value.

Table 1. Parameters
number	Any	The numeric value to format.
width	Integer	Optional, default `0`. Minimum number of characters. If the number of characters in the output value is less than the specified width, blanks are added to the left or the right of the values — depending on whether the width is negative (for left alignment) or positive (for right alignment) — until the minimum width is reached. The width specification never causes a value to be truncated.
precision	Integer	Optional, default `0`. The number of decimal places. Floating point value will be rounded accordingly.
thousandSeparator	String	Optional. String inserted between groups of three digits in the integer part. No grouping is done if omitted, `null` or empty.

Return

Formatted numeric value.
