1) I have a weight sensor hooked up to Max MSP that is giving me more accuracy than I require. How do I take floating numbers with many decimal places and reduce it to two or three?

try [sprintf %.2f] where '2' is the number of desired decimals.

Yet another solution: multiply input by 10^(desired number of decimal places); convert to integer (truncate or round as desired); divide by 10^(num-dec-place).

But note that this is largely all eye candy: Max is using 32-bit floating point, which cannot store 3.14 any more or less accurately than it stores 3.1400000625.

In a number of situations flonum will keep things to 2 sig digits after the decimal point. Otherwise sprintf is a good approach for eye candy.
