Negative number problem

[smurfier]

After about half an hours frustration I found a small problem with negative numbers. In the math world when you add a negative number to a positive number, it is the same as subtracting the positive form of that number. However, in Rainmeter all you get is a broken formula, even if it's used in a conditional statement.
There is a somewhat easy workaround:

Add a negative
#Var1#<0?#Var2#-ABS(#Var1#):Var2#+ABS(#Var1#)

Subtract a negative
#Var1#<0?#Var2#+ABS(#Var1#):Var2#-ABS(#Var1#)

And I thought I just didn't know how to write the formula... I came up with a similar solution.

There's no problem with the math in Rainmeter. Because it's a variable though, what happens is that #Var# gets replaced with the value as though it were actually there. So, if you have Formula=1+#VAR# and the value of #VAR# is -3, then while you think you would get -2 as an answer, the formula actually becomes Formula=1+-3. Rainmeter doesn't know how to deal with the "+-", so the formula fails. To avoid this, just surround your variable names with parenthesis. Formula=1+(#VAR#) should work every time. No need for conditionals.

Nice...I'll have to try that. Will make things a lot easier.

I was actually wondering how things were handled especially when figured out the difference between negative and minus.
