excel中的数字如何转成中文大写并可以在后面加上“元整”

=IF((a1-INT(a1))=0,TEXT(a1,"[DBNUM2]")&"元整",IF(INT(a1*10)-a1*10=0,TEXT(INT(a1),"[DBNUM2]")&"元"&TEXT((INT(a1*10)-INT(a1)*10),"[DBNUM2]")&"角整",TEXT(INT(a1),"[DBNUM2]")&"元"&IF(INT(a1*10)-INT(a1)*10=0,"零",TEXT(INT(a1*10)-INT(a1)*10,"[DBNUM2]")&"角")&TEXT(RIGHT(a1,1),"[DBNUM2]")&"分"))
请将上述公式复制到a2单元格中。
