How to convert a decimal number to an integer in Vue


In this short tutorial, we will see how to convert a decimal number to an integer in Vue.

If we generate a random number using Math.random() function we get random decimal numbers like this :

Random number: 46.32594933788556

Now if we want to convert these values in our vue template to an integer (eg 46), then we can use the parseInt() method.

The parseInt() method analyzes a character string that is passed as an argument and converts it to an integer value.

Syntax :

parseInt(string);

So, using this method we can convert the number to an integer by passing the decimal number in parseInt() as an argument in our Vue template.

<template>
  <div id="app">
    <div>Random number: {{ parseInt(randomNumber) }}</div>
  </div>
</template>

Full code to convert the random value to an integer:

<template>
  <div id="app">
    <div>Random number: {{ parseInt(randomNumber) }}</div>
    <button @click="generateNumber()">Generate Number</button>
  </div>
</template>

<script>
export default {
  name: "App",
  data() {
    return {
      randomNumber: "",
    };
  },
  methods: {
    generateNumber() {
      this.randomNumber = Math.random() * 100; //multiply to generate random number between 0, 100
      console.log(typeof this.randomNumber);
    },
  },
};
</script>
