Question

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

a = 0.0378
b = 0.1545

in Jade I do:

- var result = a + b*2

and I get a very strange number when I do #{result}

0.03780.309

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

Thanks

Answer 1

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

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

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