パラメーター

名前	型	方向	説明
fmt	void**	in	整形に用いるUNumberFormatハンドル。
number	LPCSTR	in	整形対象の十進数文字列。NUL終端のASCII数字で指定する。
length	INT	in	数値文字列の長さ。-1でNUL終端として扱う。
result	WORD*	inout	整形結果を受け取る出力バッファ。UTF-16のWORD配列。
resultLength	INT	in	結果バッファの容量(UTF-16単位)。0で必要長の照会も可能。
pos	UFieldPosition*	inout	整形位置情報を受け取るUFieldPosition構造体。NULL可。
status	UErrorCode*	inout	ICUのエラーコード。呼び出し前に成功値で初期化する。
