Laravel IF statement not working while inside FOR loop

Question

We are looking to increment the <option> within a <select> input type. If the option value $AccountExecutive->COMMISSION_RATE is $Rate, the <option> should be selected.

I should note that $AccountExecutive->COMMISSION_RATE is a decimal (0.5000).

We have successfully done this in standard PHP but we would like it to stay in Laravel.

              <div class="form-group">
                <label for="AE_COMMISSION_RATE">Commission Rate</label>
                  <select class="form-control" id="AE_COMMISSION_RATE" name="AE_COMMISSION_RATE">
                    <option value="0">Please enter a Value..</option>
                  @for($Rates = .05; $Rates < 1.05; $Rates += .05)
                    @if($AccountExecutive->COMMISSION_RATE == $Rates)
                      <option value="{{ $Rates }}" selected>{{ $Rates * 100 }}% </option>
                    @else
                      <option value="{{ $Rates }}">{{ $Rates * 100 }}%</option>
                    @endif
                  @endfor
                  </select>
              </div>

When comparing float values it is not recommended to do a ==, you need to come up with a way to accept tolerance, sometimes exact values in two decimals are not the same when comparing the full bits of the floats — patito, Feb 08 '17 at 18:05

Just work with integers. Let $Rates is a percent value, not fractional.

<div class="form-group">
<label for="AE_COMMISSION_RATE">Commission Rate</label>
    <select class="form-control" id="AE_COMMISSION_RATE" name="AE_COMMISSION_RATE">
        <option value="0">Please enter a Value..</option>
        @for($Rates = 5; $Rates < 105; $Rates += 5)
        @if(intval($AccountExecutive->COMMISSION_RATE * 100) === $Rates)
            <option value="{{ $Rates / 100 }}" selected>{{ $Rates }}% </option>
        @else
            <option value="{{ $Rates / 100 }}">{{ $Rates }}%</option>
        @endif
    @endfor
    </select>
</div>
