The original implementation of NumFmt did not take into account that the options delimiter (a space) could be a valid option. Adding a delim parameter seems like the simplest, safest, and most flexible way to solve this oversight in a backwards-compatible way. Fixes #5260

comments:
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.
