You can define a custom number format using special symbols to construct a format pattern. A format pattern shows places held by the currency symbol and the thousands and decimal separators. The thousands separator and the decimal separator are locale‑dependent. In the US (English) locale, for example, a comma separates thousands places, and a period separates decimal places. In most European locales, a space separates thousands places, and a comma separates decimal places.
Table 2‑2 lists example results of custom number format patterns.
