JADE中的算术运算符 [英] Arithmetic operators in JADE

问题描述

我正在将Jade模板引擎与NOde.js一起使用. 我有两个变量:

I'm using Jade template engine with NOde.js. I have two variables:

a = 0.0378
b = 0.1545

我在玉器中做

- var result = a + b*2

当我执行#{result}

0.03780.309

似乎将数字连接为字符串. 有人可以告诉我如何在Jade中使用算术运算符吗?

It seems to concatenate the numbers as strings. Could someone tell me how can I use arithmetic operators in Jade?

谢谢

推荐答案

您确定a(也是b)是数字而不是字符串吗?

Are you sure that a (and also b) is a number and not a string?

如果是字符串，则需要通过parseFloat将其转换为数字:

If it is a string you will need to to convert it to a number via parseFloat:

- var result = parseFloat(a)+parseFloat(b)*2
