有时输入可能存储为字符串。在这种情况下,我们首先需要使用 parseFloat() 函数将数字转换为浮点数,然后再使用 toFixed() 将其四舍五入到小数点后两位。 例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 constnumStr='17.23593';// 👇 convert string to float with parseFloat()constnum=parseFloat(...
In most cases JavaScript developers using Math.round() or toFixed() for rounded to the nearest integer. But, it seems like Math.round() is a better solution, but it is not! In some cases it will NOT round correctly.
