use of operators( >,<,==,!=) in ng-class

I want to use Operators to check if value is greater or equal to other number or variable in ng-class, and then apply a style class accordingly. Basically i want to color the div based on their prob.

Is the usage of ng-class correct? It prints the value of

{{1-apStats.preMappedProbability.toFixed(3)}}

but the ng-class tag doesn't work. Any reasons?

 <div ng-class="(1-apStats.preMappedProbability.toFixed(3) >=0.5) ? 'yellowClass':'redClass'"> {{1-apStats.preMappedProbability.toFixed(3)}} </div>

What am I doing wrong.? Thank you

    In ng-class directive, first you need to give class name then condition like following -

    ng-class="{moreBtnGray : condition}"

    In your case - you should use two ng-class and maintain condition accordingly. 

     <div ng-class="{yellowClass: condition1, redClass:condition2}">{{1-prob.p}} </div>
