#numbers.formatDecimal(numbwe,整数位,整数位千分位标识符,小数位,小数位表示符)
${#numbers.formatDecimal(num,1,'COMMA',2,'POINT')}
显示：99,999,999.99
1：表示整数位至少一位，不足以0补齐，如：num = 0.00，
${#numbers.formatDecimal(num,0,'COMMA',2,'POINT')}则显示 .00
${#numbers.formatDecimal(num,1,'COMMA',2,'POINT')}则显示 0.00
COMMA：','
POINT：‘.’
2：表示保留两位小数
