Each Post Doubles the Number

Simple game: double the number of the last valid post made. Just like 2048. A few rules:

1. If a post does not double the number above it, it is ignored. Do not double whatever number was in that invalid post, and do not double the previous valid number twice so as to match 2^(your post number). Simply find the last valid number and double it.

2. No double posting. You can post once a day as long as someone else has posted since your last post.

3. Scientific notation or any other base ten (no writing 2^25 etc) notation is fine, but all digits must be included; rounding is not allowed. In standard form, commas for readability are encouraged but not required. If posts start to exceed the limits of the website, then rules on rounding will change.

To start:

Reaching the character limit is very unlikely to be an issue, given that posts can have up to 60000 characters and an exponential sequence still only increases linearly in the number of digits.

I found it annoying to manually put the number into a calculator, so here's a simple perl one-liner to double a number:

Code: Select all

perl -e '$~->${;\(<,\>&>^___)}(<>=~/(((?{${$::{_}}<<!@^})))/&&*{$"^"$#+"}->$*)'
