vue3项目数字金额转大写

const toUpperCaseAmount = (value) => {
	// 将数字金额转换为大写的逻辑
	const digitUppercase = ['零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'];
	const unit = ['元', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿', '拾', '佰', '仟', '万'];
	// 小数部分----将数字转换为字符串，并按小数点进行分割
	const amountStr = String(value).split('.');
	// 整数部分转换
	let integerPart = '';
	for (let i = 0; i < amountStr[0].length; i++) {
