Uses look-up table, doesnt calculates. Only positive integers as input. The result is always 6 digit, and the decimal point can go to 3 place. Use the smallest size when sparking buttons. UPDATE 4: Simple deco for the "Error" thing. Added link to Johnny.

nice calculator

Shows error when the input number is more than 5 digit or if its higher than 16383. Try it! Just press R and it should work again.

Let me know if something is wrong. Note: I forgot to round the numbers. Example: The square root of 5 is 2.2360679, so it should be written as 2.23607, but it writes 2.23606 .

@TakMashido: The R216K2A's example program is a quadratic equation solver. To solve them it needs to calculate square roots. And it does that with floating points. And its fast. So, the R216K2A calculate square roots faster than this, WITH floating points! (and that's actually calculating)

The filt pattern is interesting.

Hmm LUT calculator. A bit strange but normal square root formula is too complicated to run fastly in tpt(yet?).
