floating point number conversion (exponent)
Hi all,
wow, I just see the post was corrupt. Now I correct it again.
I have a text file with float numbers in the format as below - namely with the exponent at the end. I would like to parse / transform these values so I can work with them in max like the other regular floats.
Does somebody have an idea?
All the best, Frank

Regexp seems like a good place to start. I found this post https://codereview.stackexchange.com/questions/8428/python-program-for-converting-scientific-notation-to-fixed-point added extra slashes to make it Max-friendly. It's not all the way there, but maybe you can build on it. I'm not a regex wizard (only learn enough to solve the problem at hand...) and there are clearly problems: for example, the leading - is stripped.
It's probably easiest to use a language that can handle scientific notation natively to dump the data into max - e.g. javascript. Create a literal array with your data and bang it out. Something like this should do it:
var data = [2.407984776842665653e+00, 1.026246200945576947e-01, -4.199148397133440902e-01, ..., and_so_on, ...];
function bang() {
outlet(0, data);
}
wolfram alpha takes arrays, too, but i think there is a limit of 10 or so.
