Question

'This is the variable which I want to express in absolute value .

<%= rate-32.5   =%>

However ,I tried

<%= |rate-32.5  |=%> 

It doesn't work .

And I guess there is no this method in ruby .

Answer 1

Use this link for more details of .abs ruby method.

abs → numeric

Returns the absolute value of num.

  12.abs              #=> 12

  (-34.56).abs        #=> 34.56

  -34.56.abs          #=> 34.56

So you use .abs function for your solution like this (rate-32.5).abs
