// FormatNumberCustom formats a number with the given precision using the
// negative, decimal, and grouping options. The `options`
// parameter is a string consisting of `<negative> <decimal> <grouping>`. The
// default `options` value is `- . ,`.
// FormatNumberCustom formats a number with the given precision. The first
// options parameter is a space-delimited string of characters to represent
// negativity, the decimal point, and grouping. The default value is `- . ,`.
// The second options parameter defines an alternate delimiting character.
//
// Note that numbers are rounded up at 5 or greater.
// So, with precision set to 0, 1.5 becomes `2`, and 1.4 becomes `1`.
