Can you give me half?

+11
−0

Challenge idea taken from: Eliseo D'Annunzio

Task

Provide code that evaluates to 0.5 numerically, i.e. the output must be recognized by your chosen language as a numeric value (Number, float, double, etc), not as a string.

The catch, the characters 0 through to 9 cannot be used.

One example that fits the brief would be the following:

((++[[]][[~~""]]<<++[[]][[~~""]]))**((--[[]][[~~""]])) which works out to 0.5 in JavaScript.

Scoring

This is a code challenge, where scoring is done in terms of number of unique characters used in the submission. Ties are broken by lowest bytecount.

J, 4 3 distinct, 6 bytes

-:_-:_

Half of _ -: _ which is asks if infinity matches infinity. Thanks to @xash in the APL farm discord for saving the 3 unique bytes and orthoplex for catching my blunder.

Ah yes, I made an error there. Sorry, about that.
