Javascript – How to generate a number range with N decimal places

I need to generate a large array of numbers ranging from 0.00 to say 10000000.00
i.e
0.01
0.02
0.03
…
1.51
1.52
1.583
… etc

After looking around, I tried this answer which works fine for integers but however not working for decimals

    You didn’t specify a language, so I will use Python.

    import numpy as np

numbers = np.arange(0, 10000000.01, 0.01)

# Print first 10 elements
print(numbers[:10])

# Print last 10 elements
print(numbers[-10:])

    A simple way, try this:

    let array = [];
for (let i = 0; i <= 1000000000; i++)
{
   array.push(i * 0.01);
}

    const arr = Array.from(new Array(10000000), (_, index) => (index / 100).toFixed(2));

console.log(arr);

    With this code, you will get an array of the numbers described in the question, after the dot there will be 2 numbers: 0.00, 0.01 and so on.

    Try the following

    let array = [];
let val = 0.00;
do{
   val += 0.01;
   array.push(val);
}while(val<1000000000.00);
