Why can't I do multiple calculations using $calc?

You can.

(If you want a more elaborate answer, provide a more detailed question.)

I assume the question you were trying to ask is why don't you get the result you expected. The answer is operator precedence. Mathematical operators (eg. +, -, /, *) have different precedence (priority) which means that in an equation like the last one in your example each operation does not necessarily occur from left-to-right. Precedences for the operators $calc() supports are as follows (from highest to lowest):


So to use your example again -- 1194 - 1 / 1679 * 100 -- because / and * have higher precedence than - they are performed first and then the result is subtracted from 1194 giving you 1193.940441.

You can force operations to be performed in a certain order by using parentheses. For example (1194 - 1) / 1679 * 100 would give you the answer you expected

lol Genius, let's just assume his question is "How can I perform multiple calculations with $calc?"

The answer is surprisingly found in the mIRC help file! Go figure ....

Ah of course, thanks ;P
