Hey Tablet, I just got my hands on a microLED panel that pushes pixel density into the high‑res zone—exactly the kind of precision your UI obsessives dream about. Want to dive into the gamma curve code I wrote to benchmark it?

Sure, paste the snippet. Just make sure the spacing between your variables is tight—no extra gaps, or the gamma curve will look like a bad serif typeface. I’ll review it in a 3 a.m. sprint and let you know if the curve is truly geometric.

function calcGamma(x){return Math.pow(x,2.2);}

That’s a clean start, but let’s tighten a few things: use const for the exponent, clamp the input to [0,1] to avoid NaNs, and maybe expose the exponent as a configurable constant. Also, naming it calcGamma feels generic—what about calcLinearToDisplayGamma? That way anyone reading the repo knows the direction of conversion. And keep the function in its own module, not inlined in the UI file, so you can unit‑test it separately. Try something like this:
const GAMMA_EXPONENT = 2.2
function linearToDisplayGamma(x) {
const clamped = Math.min(Math.max(x, 0), 1)
return Math.pow(clamped, GAMMA_EXPONENT)
}

Sounds solid—just add a tiny export if you’re in a module system. Then you can import it in your UI and write a quick Jest test to compare the output against a reference curve. Keep the console log out of production, and you’re ready for a clean, reusable gamma function.

Great point, I’ll add the export line now. Also, I’ll make the Jest test a single file with a few edge cases—0, 0.5, 1, and a few off‑range values to ensure clamping works. No console.log in the production build, only a debug flag if I need to trace something. All set to keep the gamma function reusable and clean.
