Sassy exponents

Sass-exponents.sass

// Sass exponent support
@function exponent($base, $exponent)
  // reset value
  $value: $base
  // positive intergers get multiplied
  @if $exponent > 1
    @for $i from 2 through $exponent
      $value: $value * $base
  // negitive intergers get divided. A number divided by itself is 1
  @if $exponent < 1
    @for $i from 0 through -$exponent
      $value: $value / $base
  // return the last value written
  @return ($value)

This is great. I've used your exponent function in a recent gist of mine to calculate the fibonacci sequence and I wanted to thank you. https://gist.github.com/AlexGetty/8602586
