示例：
var data = 12345;console.log(numberToChinese(data));//结果:壹万贰仟叁佰肆拾伍元var data = 12345.12345;console.log(numberToChinese(data));//结果:壹万贰仟叁佰肆拾伍元壹角贰分叁厘肆毫var data = 0;console.log(numberToChinese(data));//结果:零元var data = 0.234;console.log(numberToChinese(data));//结果:零元贰角叁分肆厘var data = -345.89;console.log(numberToChinese(data));//结果:负叁佰肆拾伍元捌角玖分var data = -10004.89;console.log(numberToChinese(data));//结果:负壹万零仟零佰零拾肆元捌角玖分var data = 50000;console.log(numberToChinese(data));//结果:伍万零仟零佰零拾零元var data = 50000.0004;console.log(numberToChinese(data));//结果:伍万零仟零佰零拾零元
