Patch
Added in 6.0.2 / 1.13.2

Divides digits into groups using a localized delimiter character.

valueString = BreakUpLargeNumbers(value)

Arguments

valueString: string - The whole-number portion converted into a string if greater than 1000, or truncated to two decimals if less than 1000.

Large numbers are grouped into thousands and millions with a LARGE_NUMBER_SEPERATOR, but no further grouping happens for even larger numbers (billions).
Small numbers with a decimal portion are separated with a DECIMAL_SEPERATOR and truncated to two decimal places.
Not intended for use with negative numbers.
