Syntax
lang.NumFmt PRECISION NUMBER [OPTIONS [DELIMITER]]
The default options value is - . ,. The default delimiter within the options
value is a space. If you need to use a space as one of the options, set a
custom delimiter.
Numbers greater than or equal to 5 are rounded up. For example, if precision is set to 0, 1.5 becomes 2, and 1.4 becomes 1.
