What causes the Bullet chart to display decimal numbers despite having a range of 1?

I am currently utilizing the nvd3-bullet-chart from the angularjs-nvd3-directives library to showcase maximum and current data. It functions properly when my minimum number is greater than 2, displaying whole numbers. However, if my maximum number is set to 1, it displays decimal numbers instead. How can I eliminate these decimal numbers? Any assistance on this matter would be greatly appreciated. Thank you.

var app = angular.module('plunker', ['nvd3']);

app.controller('MainCtrl', function($scope) {
    $scope.options = {
        chart: {
            type: 'bulletChart',
            transitionDuration: 500,
            height: 70,
            margin: {
                top: 10,
                right: 10,
                bottom: 30,
                left: 125
            }
},
title: {
    enable: true,
    text: 'Title for Line Chart',
    css: {
    'text-align': 'center',
    'font-size': '12px'
}
}



};


$scope.dataset = {

data: {
"title": "Revenue",
"subtitle": "US$, in thousands",
"ranges": [1],
"measures": [0],
"markers": [0]
},
data2: {
"title": "Revenue",
"subtitle": "US$, in thousands",
"ranges": [150, 225, 300],
"measures": [220],
"markers": [250]
}

}
});

Have you considered using a different approach instead of tickFormat?

Check out this code snippet that demonstrates the formatting of tick values using %:

var app = angular.module('app', ['nvd3']);

app.controller('MainCtrl', function($scope) {
  $scope.options = {
    chart: {
      type: 'bulletChart',
      transitionDuration: 500,
      height: 70,
      margin: {
        top: 10,
        right: 10,
        bottom: 30,
        left: 125
      },
      tickFormat: function(d) {
          return d3.format('%')(d);
      },
    },
    title: {
      enable: true,
      text: 'My Chart',
      css: {
        'text-align': 'center',
        'font-size': '14px'
      }
    }

  };

  $scope.data = {
      "title": "Revenue",
      "subtitle": "%",
      "ranges": [0, 1],
      "measures": [0.1],
      "markers": [0.5],
  }
});
