I have this ChucK code:
"examples/vento.txt" => string filename;
FileIO fio;
// open a file
fio.open(filename, FileIO.READ);
// ensure it's ok
if(!fio.good()) {
cherr <= "can't open file: " <= filename <= " for reading..." <= IO.newline();
me.exit();
}
fio.readLine() => string velocity;
fio.readLine() => string direction;
The text file contains:
10
12
(it's updated with python every minute)
I want to convert velocity and direction to int (or better float).
How can I do this?
Use
atoi
andatof
in theStd
library. Let's say you want to translate from 0-127 (MIDI velocity) to a float between 0 and 1.0 (much more convenient for unit generators):should print
0.078740 :(float)
for an input of 10.Or if you want to just go straight to float:
which prints
10.000000 :(float)
.
