Faker.js 2个值之间的随机数 [英] Faker.js random number between 2 values

问题描述

这使我发疯了，我敢肯定这很简单，但似乎没有任何地方记录在案.

This one is driving me a little mad, I'm sure it's simple but it doesn't seem to be documented anywhere.

我正在使用 Faker.js 和以下内容生成我的随机数:

Im using Faker.js and the following to generate my random number:

faker.random.number();

很好，现在，如果我想在2个数字之间进行运算，我将如何处理?

Works great, now if I want to do it between 2 numbers, how would I go about this?

我尝试了以下操作:

faker.random.number(10, 50);

但是，这只能为我提供从 0 到 10 的数字.不知道 50 在做什么.

However, that just gives me numbers from 0 to 10. No idea what the 50 is doing.

任何人都可以给我一些指导.

Can anyone give me some directions to this please.

推荐答案

您需要为该函数提供一个对象:

You need to give an object to the function:

faker.random.number({
    'min': 10,
    'max': 50
});

因此，如果您仅传递数字，它将设置为最大值.最小值默认为0.

So if you just pass a number, it will set it as the max value. The min value is 0 by default.

这是数字功能的实现:

this.number = function (options) {

    if (typeof options === "number") {
      options = {
        max: options
      };
    }

    options = options || {};

    if (typeof options.min === "undefined") {
      options.min = 0;
    }

    if (typeof options.max === "undefined") {
      options.max = 99999;
    }
    if (typeof options.precision === "undefined") {
      options.precision = 1;
    }

    // Make the range inclusive of the max value
    var max = options.max;
    if (max >= 0) {
      max += options.precision;
    }

    var randomNumber = options.precision * Math.floor(
      mersenne.rand(max / options.precision, options.min / options.precision));

    return randomNumber;

  }
