Hi,

To truncate, simply use [int]. To round, add 0.5 to all the values before you truncate. If you need something statistically less biased (the above method of rounding will round everything with a fractional value of exactly 0.5 up to the nearest integer, which could cause some positive drift in certain circumstances) -- you can use [expr rint($f1)], which I think will round fractional values of 0.5 to the nearest even integer (5.5 -> 6; -122.5 -> -122, e.g.).

Thanks,

Matt

Hi there.

i've been lurking here for 4 or 5 months now, and this community is really excellent; i've learned a lot. But now i have my first question: Is there an easy way to make a number like 76.87731 round up/down or even just chop off the decimal places? i'm sending these numbers as MIDI controller numbers and would like to be able to see them the way the MIDI device does, as a simple number between 0 and 127.
