Odd about the I2C - have you tried different micro:bits? I guess it's possible yours has a dodgy connection?
For
show, it's tricky - Math.pow will be using floating point, and I believe the truncation (rather than rounding) is the correct thing to do. The micro:bit has so little memory I believe I'm using a simplerMath.powthat's not quite as accurate, which might account for the problem. I'm not sure there's an easy fix (short of just hackingshowto round when it gets an FP number).
