问题描述
我该怎么办？ Javascript中的 0.075 到 0.08 的圆形浮点数？
How can I round floats such as 0.075 up to 0.08 in Javascript?
推荐答案
你需要乘以一百（以便分数将被舍入），舍入，然后除以一百来再次以美元获得合适的价格。
You need to multiply by a hundred (so that the cents are what will get rounded), round, then divide by a hundred to get the right price in dollars again.
var dollars = 0.075; // 0.075 dollars
var cents = dollars * 100; // ... is 7.5 cents
var roundedCents = Math.round(cents); // ... but should really be 8 cents
var roundedPrice = roundedCents / 100; // ... so it's 0.08 dollars in the end
