Calcsimple < SIMPLE >

Use parseFloat and toFixed(10) to avoid floating point noise. [ CE ] clear last number [ C ] clear everything [ M+ ] store display to memory [ MR ] recall memory [ MC ] clear memory Percent rules: A * B% = B% of A A + B% = A + (B% of A) A - B% = A - (B% of A)

function calculate() let result = eval(prev + lastOp + current); // simplistic display = result; waitingForOperand = true; calcsimple

Shortcuts: Enter = = Delete = CE m r c = M+ MR MC q = √ CalcSimple is not for calculus, matrices, or programming. It’s for speed in daily life — splitting a check, calculating a tip, scaling a recipe, figuring out sale prices. Mastering it means you never reach for a phone, unlock it, open an app, wait for ads, and tap tiny buttons again. You just type. Use parseFloat and toFixed(10) to avoid floating point noise
