Subtract numbers in .tpl

[Daniel Kück]

Hey mates,

how can I subtract two variables in the template file?

E.g:
<span class="human-readable-number">{topics.postcount - 1}</span>

Do you mean subtract?

[Daniel Kück]

@pitaj yes, sorry my bad

Benchpress had no built-in way to do this. You'll need to add a helper in order to do subtraction.
