number to the zero power() is one

[demrks]

In math any number to the zero power is one, so

power(2, 0);

should return "1", but it returns return "4"

FYI -- I submitted a pull request about a week ago that resolves this issue. @adambom @demrks

I'm late but you just have to replace this statement : @if $n >= 0

With this one: @if $n > 0

By doing that, when $i == 0 the loop looks like this : @for 1 from 0 to 0 This means that the loop stop right before 0... So the loop don't start and the function return 1
