Generate Random Numbers in Make.com: A Quick Guide

In this quick guide, I’ll share several methods for generating random numbers tailored to your needs.

Whether you’re looking for a random number between 1 and 10 or a 10-digit random number, in a bit you know how.

Let’s dive in! 🙌

Random number between 0 and 1

Don’t have any requirement to the number? The easiest is to use the random variable:

As you can see, this will generate a random number between 0 and 1 (but not including 1) with 16 decimal places:

random

= 0.5297136290576396

So if that’s all you need, great!

If you need a whole number, or a random number between certain values, keep reading 🤓

Random number between 1 and 10

To get a whole number between 1 and 10, we can use the random variable with some math functions.

First, we multiply the variable by 10 so we get a number between 1 and 10 with decimals:

random*10

= 8.364132191975076

Then, we use the floor() function to round it down to the nearest whole number.

floor(random*10)

= 8

This will now give us a number from 0 to 9, so simply add 1 to the formula to get a number from 1 to 10.

floor(random*10)+1

= 6

Easy, right?

Random number between 1 and 6

Want to create a fun dice game? 🎲

You can use the same method as above, but then multiply the random variable by 6.

floor(random*6)+1

= 4

Random percentage

Useful for probability-based automation where you need a percentage value.

This formula essentially gives you a random number between 1 and 100.

floor(random*100)+1

= 48

Or if you need the percentage with it, surround the formula in brackets and add the percentage symbol.

(​floor(random*100)+1​)%

= 62%

Random number with 10 digits

Need a long random number?

Multiply the random variable by 1000000000000 if you for example want 10 digits, and use the round() function to round it to the nearest whole number.

round(random*10000000000)

= 3029472548

Or multiply by 100000 if you want 5 digits. Simply change the amount of zeros for the amount of digits you want.

round(random*100000)

= 93728

That’s it!

Random round-robin

Want to split data evenly across multiple routes in a scenario?

To make sure each route gets an equal share, a round-robin approach is ideal.

In this case, the numbers aren’t purely random since we want every number to appear equally.

To achieve this, use the increment function along with the formula below.

(1. i+1)%3

= 0, 1 or 2

This will return 0 on the first scenario execution, then 1, then 2, and then loop back to 0 again.
