round()函数用于舍入数字或浮点数。我们可以将数字四舍五入到所需的小数位。使用此函数的正确语法如下 round($number,$decimalPlaces,$mode); 示例代码: <?php$number1=5;$number2=34.6;$number3=15439.093;$format_number1=round($number1,2);$format_number2=roun
例如,ROUND(10.004,2) 返回 10,而不是 10.00。...当舍入到固定的小数位数很重要时使用 $JUSTIFY - 例如,在表示货币金额时。 $JUSTIFY 在舍入操作之后返回指定数量的尾随零。当要舍入的位数大于小数位数时,$JUSTIFY 补零。 如何在 JavaScript 中将数字四舍五入到小数点后两位 = Number(num.toFixed(2)); ...
