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): Code: Operator \| Description ---------------------- ^ \| Exponentiation (power of) , /, % \| Multiplication, Division, Modulus +, - \| Addition, Subtraction 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 Spelling mistakes, grammatical errors, and stupid comments are intentional.

The answer is surprisingly found in the mIRC help file! Go figure .... Quote: $calc(operations) Returns the result of the specified operations. This identifiers allows you to perform multiple operations easily. For example: $calc(3.14159 * (2 ^ %x % 3) - ($ticks / (10000 + 1)))
