format-number

Description

Provides numeric formatting for thousands separators, fixed precisions, and trailing zeroes.

By default, numbers are formatted only with thousands separators added. Any decimal places in the original number are preserved without any change in precision.

By specifying a precision only, any decimal places will be truncated to that as a maximum precision. The decimal places will not, however, be padded out with zeroes unless a positive integer (anything > 0) is passed as the third operand.

Usage

<number> [<precision> [<trailing zeroes>]]

Examples

:emphasize-lines: 2,5,8

(format-number 12398123)
"12,398,123"
