For fixed precision, you can either use an explicit format as Russell Adams
points out,
or you can modify (globally or per file) the variable org-calc-default-modes.
That's a
complicated variable and you only need to change one part of it for this:
(plist-put org-calc-default-modes 'calc-float-format '(fix 2))
See e.g. https://emacs.stackexchange.com/a/59181/14825 for some discussion.
