parameter export adds too many trailing zeros.

.param files are messy to read due to all the trailing zeros.
To illustrate, I attached a meld comparison between a cleaner version (basically an export rounded to up to 8 decimals), and current output.

I assume this a 1-minute fix for somebody out there :)

Start by locating the parameter export entry point that produces .param files and inspect how numeric values are formatted. Compare the current output with the cleaner example in the issue. Done means exported parameters avoid unnecessary trailing zeros while retaining up to 8 decimal places.
