Write Sass function called double

Question

Hi guys,

I'm getting stuck in the challenge "speeding up Workflow with Sass". The challenge is: " Write a function, called 'double', that multiplies its input by 2. "

I've tried the following thing: @function double{ @return $input($value * 2); }

Thanks.

Mardi, you pretty much got it right. You don't need the ( ) or the ; after your @return .

Also, check the rest of your code. I wasn't passing because I had 'fontsize' and not 'font-size'

Hey guys!

Here the right code for it:

@function double($input) { @return $input * 2; }

Cya! :-D

I was stuck on this too, until I omitted the parentheses around the return value

You're not passing in a parameter. The function must take one parameter (which is the input to double). Then when the function returns a value, just return that parameter * 2. return $input($value * 2) isn't valid code.

Hi guys, getting stuck on this to. I'm sure I had it when I used the following code. Not so lucky..

@function double($input) { @return($input * 2); }

Also I tried it with the 'unquote' function, but that didn't help. Any ideas?
