温度转换器 [英] Temperature Converter
问题描述
我完全坚持使用这个。
我必须创建一个温度转换计算器，将结果温度四舍五入到最接近的整数&反之亦然。结果必须显示在窗口警报中。给定的公式是（Fahrenheit_temp - 32）* .55
我唯一的提示/线索是使用
var tempInCelcius =（document.Converter.fahrenheit.value - 32）* .55;
var tempInFahrenheit =（document.Converter.celcius.value * 1.8）+ 32
我试过，删除，试过和再次删除。我很沮丧，感到自杀，我只是没有理解这个概念。
请帮助！

I am absolutely stuck with this one.
I have to create a temperature conversion calculator that rounds the resulting temperature to the nearest whole number & vice versa. The result must be displayed in a window alert. The given formula is (Fahrenheit_temp - 32) * .55
The only tip/clue I have is to use
var tempInCelcius = (document.Converter.fahrenheit.value - 32) * .55;
var tempInFahrenheit = (document.Converter.celcius.value * 1.8) + 32
I have tried, deleted, tried and deleted again. I am so frustrated and feeling suicidal that I am just not grasping the concept.
PLEASE HELP!

推荐答案
使用Math对象。它有圆形，地板和其他可以使用的方法。
Use Math object. It has round, floor and maybe other methods you can use.
