I often have to generate a sequence of cube numbers so I created this simple utility that does it for me. It lets you generate however many perfect cubes you need, starting from any value. It works in the browser and is powered by alien technology from the future.

^{3}to 49

^{3}. The calculation starts from the 0th position and continues to the 49th position. The cubes are printed individually on each line (the separator is the newline \n) and the output radix is 10 (decimal).

^{3}) in base-10, the next value is 533, which is 1331 (11

^{3}), and so on.

## How Does This Cube Number Sequence Generator Work?

This perfect cube list generator works entirely in your browser and is written in JavaScript. It uses two JavaScript libraries to compute the cubes. The first library is `decimal.js`

and the second one is `bignumber.js`

. The decimal library is used to test if the starting value is a cube. Unlike the big number library, it's able to perform the cube root operation. If the starting value is not a cube, then this tool finds the next closest cube and starts calculating cubes from this value. The formula for finding the closest cube is `round_down(cbrt(val))+1`

, where `round_down(x)`

rounds down `x`

to the closest integer and `cbrt(x)`

finds the cube root of `x`

. All cube calculations are done using the big number library as it works well with integers. To create a sequence of cubes, it creates a loop from `1`

to `count`

(number of sequence elements, specified in options) and in every loop step, it multiplies the current cube number, stored in the `currentCube`

variable by itself three times, and saves it in an output list `cubesOut`

in the given base (specified in options). At the end of the loop, the cubes in `cubesOut`

are printed one after another with the `separator`

(specified in options) symbol between them.

### Created by Browserling

This cube number sequence generator was created by me and my team at Browserling. Behind the scenes, it's actually powered by our web developer tools that are used by millions of people every month. Browserling itself is an online cross-browser testing service powered by alien technology. Check it out!
