ng-pattern仅适用于没有小数的数字

Question

Need ng-pattern for restricting entry of decimal in input type number.I have used ng-pattern="/^[0-9]$/" to get the result but its not showing error on 1.0,2.0,3.0 etc. Example:

2.0 = fail
2 = pass
3.0=fail
3=pass

<div class="col-md-5 col-md-offset-7">

<input type="number"  min="0" class="form-control" id="equalizingFactor" 
 name="equalizingFactor" ng-model="flatVariable.equalizingFactor" 
 itle="Equalizing Factor" ng-maxlength="3" ng-pattern="/^[0-9]$/" 
 message="The field should contain only numbers with no decimal places"
 ng-readonly="flatVariable.pgmInd30"/>

</div>

Should only have numbers no decimals included.

These should work fine:

ng-pattern="/^[0-9]*$/"  // 0 or more numbers

ng-pattern="/^[0-9]+$/"  // 1 or more numbers

ng-pattern="/^\d*$/"     // 0 or more numbers

ng-pattern="/^\d+$/"     // 1 or more numbers
