[Smantii]

Fixes compilation error in the double-precision Operon backend.

As it stands, there are unneeded changes. We only need to keep these:

Done!

Done!

Hi, sorry for being pedantic but we don't want to have all these commits in the history (the last one basically reverts the previous changes). Instead, please soft-reset to HEAD~3, then commit only the required changes and force-push.

[Smantii]

Done, now the changes are made in a single commit.

Looks good, thanks!
