Sorry to come back to this with a huge delay, but in fact I don't have any
experience with Calc mode at all! I can't answer your questions without
digging the manuals.
The only thing I make use of is inline Calc for simple computations, to avoid
making mistakes in prices (fictitious example):
--8<---------------cut here---------------start------------->8---
The work will last 20 days and cost src_calc[:results raw]{20 * 498} USD at
the base rate.
--8<---------------cut here---------------end--------------->8---
Best regards,
Seb
