Random Binary

Ones and zeros, as many as you ask for. Grouped into bytes because eight in a row is unreadable and thirty-two is worse.

Each bit is its own coin flip

The string is not a random number written out in base two — it is one draw per bit. That matters at the front: a random number below 2^16 starts with a zero half the time, and a string of sixteen coin flips does too, but for a different reason.

The decimal value underneath is the whole string read as one unsigned number, which stops being useful past about fifty bits.

What it is for

Teaching, test data, and filling in the parts of a diagram that are meant to be arbitrary. It is not a random number generator with extra steps — /number is that.

Nothing is sent anywhere; the draw stays in this browser.
