I've been storing floats in sysex messages using fudiformat and restoring them using fudiparse, but this suffers from the same display format truncation that many Pd float persistence facilities do. For instance:

It's a tiny difference, but one of my patches is sensitive to it.

I started to make something to break up the 32 bits of a single precision float into 5 words, 7 bits each, but I forgot that the bitwise operators in Pd convert the float to an integer first. Silly moi.

When I'm just saving to and restoring from a file, I use an array as intermediate storage and then use soundfiler to write/read the array to/from file. I just tell soundfiler that the array contains 4 byte samples. But it would be nice to use sysex so that I can record, edit, and playback a sequence of them. Is there a way to do this?

What about implementing your own fixed or floating point encoding for sysex? Break the float into two ints at the decimal, first first bit of the message is the length of the first int, reconstruct after the fudiparse?

Edit: Suppose a simple integer based fp implementation would not actually work here, did not think that through.

A little ridiculous, had to jump through some hoops to get that symbol back into a float. I used the -u flag of [fudiparse] so I could just use a simple [list split] in an earlier version but [fudiparse] and [fudiformat] should drop in now. There is some external which would make the symbol to float conversion easier but I can never remember which one it is and I have been trying to figure out the logic of why some float symbols will not convert with [float] and they weirdly are not even consistent regarding which hoops you have to jump through, first time I had to form a list and put it into a [text].

@oid Thanks! I think I'm gonna go with [makefilename %.7e] to reduce the word count to 13 per float and probably just use fudiparse to convert back to float. It would've taken me a while to figure out that I had to strip the leading "symbol " selector, so thanks for saving me that effort.
