With this browser-based program, you can add visual separators between every n digits of an integer. By default, every three digits get separated by a comma but you can change the separator symbol that goes between the digits. The separators get added from the low end of the integer but you can also make it work the other way from the high end. Created by math nerds from team Browserling.
This online utility lets you insert delimiter characters between a certain number of integer digits. For example, if you have an integer 1234567, then to make it easier to read, you can insert an apostrophe between every 3 digits and get 1'234'567. The character that gets inserted between the digits can be changed in the options. The most common thousands separator characters are a comma (1,234,567), a dot (1.234.567), and a space (1 234 567). In these examples, the digits are counted from the end. You can also count the digits from the start. In this case, you will get 123'456'7. A common trick to memorize large integers (such as the fractional part of the constant π) is to separate every 5 digits or 6 digits. The fractional part of π is 1415926535897932384626433 and if you change the digit count (in the options) to 5, you will get 14159 26535 89793 23846 26433 in the output, which is now very easy to memorize. Integerabulous!
In this example, we insert commas in a large integer between every three powers of ten, starting from ones. The ones, tens, and hundreds get separated by a comma, then thousands, ten thousands, and hundred thousands get separated by a comma, and so on. The new value with commas creates an easy-to-read version of the integer that lets you estimate its order via subitizing. It's now easy to see that the value is about 5 trillion as there are four commas with three digits between them, so the order is 104×3 = 1012, which is trillions.
In this example, we convert a list of the first eight perfect integers into a new representation that lets us easily memorize them. Just as a reminder, a perfect integer is one whose sum of all its divisors is equal to the integer itself. There are just a few perfect values and they grow very fast. The first four are easy to memorize as they have four digits or less but the larger values are hard to memorize as there are so many digits. The new representation inserts a middle dot character between every four digits, breaking them into smaller sets that can now be individually memorized.
In this example, we separate individual integer digits and place each digit on a new line. To accomplish it, we set the digit counter equal to "1" and the separator character equal to "\n" in the options. This way, every digit gets separated by a new line character, which flips the eight-digit integer from the horizontal position to vertical.
