在这个例子中,我们创建了一个 removeTrailingZeros() 函数。函数首先查找数字字符串中的小数点,并将其索引保存在 decimalSeparatorIndex 变量中。然后,它从字符串的末尾开始查找,直到找到第一个非零数字。最后,函数返回一个新的数字字符串,它的长度与最后一个非零数字相同,这样就删除了所有尾随零。
You can use the parseFloat() method to remove trailing zeros from a number in JavaScript. The parseFloat() method parses a string into a floating point number while removing all the trailing zeros. const num = 3.50000 const res1 = parseFloat(num) console.log(res1) // 3.5 // parse the...
