I just started playing with SmartBat and I found the Evaluate function. So, to get a feel for things, I tried a few expressions:
2+4 = 6 (Okay) 2*4 = 8 (Looking good...) 5^2 = 7 (What!?! 5 squared is 25. Wait a minute. What if...) 1^1 = 0 (Yup! It's XORing not raising to a power.) 1|2 = 3 (And this is OR) 1|2|4 = 7 (So it this) 7&1 = 1 (This is AND) 4&1 = 0 (So it this) 5**2 = 25 (That's better!) 2*5**2 = 100 (Hunh? It should be 50.) 2*(5**25) = 50 (Ah! A problem with the order of operations.) sqrt(25) = Error (No sqrt [square root] function? Oh well...) 25**.5 = 5 (I know how to get around that problem!) Everything seems to make sense (after I got over the binary math) except this: 2*5**2 = 100 (Hunh? It should be 50.) This seemed to be evaluated as: (2*5)**2 (10)**2 100 and not 2*(5**2) 2*(25) 100 If I remember correctly, in the order of operations (PEMDAS), exponentiation comes after parentheses and before multiplication and division, which come before addition and subtraction. So, is this a problem with SmartBat's Evaluate function, the %CALC macro, the library (if any) RitLabs used to implement this functionality, or my memory? -- Chris Quoting when replying to this message is good for your karma.
