Usage Info

The input type is detected automatically on entry.

Pressing the output will copy to the clipboard.

Input Types

Decimal: Positive integers up to 2^64 - 1
Hexadecimal: Must start with 0x (e.g., 0xFF)
Text: ASCII printable characters (codes: 32-126)
dollcode: ▖, ▘, and ▌ characters

Buffer Limits

Maximum decimal length: 20 (u64::MAX)
Maximum hexadecimal length: 18 (0x + u64::MAX)
Maximum text length: 100 ASCII-printable characters
Text encoding: variable length from 3-5 dollcode characters plus a zero-width joiner, resulting in an maximum output of 18 bytes per character

The output buffer is set so a max-length dollcode output can still be decoded.

What?

dollcode is a trinary encoding system. It uses three Unicode box-drawing characters to represent base-3 digits:

Numbers are encoded by looping through and checking each modulus 3 result, then replacing it with one of the three characters.

Text is done by encoding each character's numeric ASCII code value into a variable-length dollcode sequence, appended with a zero-width joiner.

The most significant bit is on the left side.

Examples:


                    
                        numbers: 1-16 → ▖ ▘ ▌ ▖▖ ▖▘ ▖▌ ▘▖ ▘▘ ▘▌ ▌▖ ▌▘ ▌▌ ▖▖▖ ▖▖▘ ▖▖▌ ▖▘▖
                    
                    
                        longer number: 42 → ▖▖▖▌ [1×27 + 1×9 + 1×3 + 3]
                    
                    
                        hexadecimal: 0xFF → ▘▘▌▌▌ [255 in decimal]
                    
                    
                        text: hey :] → ▌▘▖▘‍▌▖▌▘‍▖▖▖▖▖‍▌▖▘‍▖▌▖▖‍▘▌▌▌‍
