Integer enumerator
World's simplest integer tool
This online utility enumerates the integer set and prints the enumerated integers as a comma-separated sequence. You can choose the enumeration range or choose the output sequence length. The integer sequence can cover any range and be of any length. The output sequence format and individual integers can be further customized by adjusting the enumeration format options. Created by math nerds from team Browserling.

What is a integer enumerator?
learn more about this tool
With this webapp, you can create a list of increasing or decreasing integers. The list starts with the given start value that you can change in the options and then you have two choices. You can either set the end value, in which case, the generated integer sequence will continue to this value, or you can set the sequence length, in which case, you will get that many elements in the output. You can also adjust the distance between two neighbor integers through the step option. For example, if the start number is 100, the end number is 200, and the step is 50, then you'll get three numbers in the output "100, 150, 200". If you're using the sequence length option and set it to, let's say 5, then you'll get five numbers in the output "100, 150, 200, 250, 300". To customize the output, you can use five different options. First, you can change the symbol that goes between integers. By default it's a comma but you can change it to a new line, a space, or any other character. Second and third, you can change the symbols that go before and after each integer. By default, they are empty symbols and nothing gets printed before or after integers. Finally, the last two options let you set the symbols that go before and after the entire output enumeration. These options are also empty by default. Integerabulous!
Integer enumerator examples
Click to useNatural Ordering
In this example, we output the natural ordering of positive integers. We use the Generate a Range option to enumerate the integers from 1 to 100 and set the enumeration delta to 1, which means the output set covers every integer from 1 to 100.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100

Negative Integers
This example uses the Generate a Specific Count of Integers option and outputs a set of eleven integers. The first set value is zero because the start option is set to 0. The other ten elements are negative integers because the step value is set to -10, so each time the next value is enumerated, it's 10 less than the previous one.
{0, -10, -20, -30, -40, -50, -60, -70, -80, -90, -100}

Concatenated Integers
This example generates a concatenated string of increasing integers from one to one hundred. As the sequence separator is set to the empty symbol, there are no spaces between the integers and the output is a huge number.

Constant List of Integers
In this example, the integer change is set to 0. That means the same starting value gets enumerated over and over again. As a result, only the integer 50 gets printed for 20 times. The output separator is set to a newline symbol and the integers are printed in a vertical column.

Fun With Integers
In this example, we're having fun and decided to decorate the integers. Each integer is wrapped in a pair of angle brackets, and the entire integer sequence is wrapped in a pair of grinning emojis.

Array of Arrays
In this example, we use opening and closing square brackets in the enumeration format options to create a JavaScript array of arrays of integers. We separate the internal array items with a comma and generate an array of thirty odd integers, starting with the value 1.
[[1], [3], [5], [7], [9], [11], [13], [15], [17], [19], [21], [23], [25], [27], [29], [31], [33], [35], [37], [39], [41], [43], [45], [47], [49], [51], [53], [55], [57], [59]]
