Order of operations?

[Gamemaster1494]

Does vb6 follow the order of operations? (parenthesizes, exponents, multiplication, division, addition, subtraction)

[Ellis Dee]

For the most part, yes. As a general rule I would go with parentheses.

An example where it breaks down is the "\" integer-division operator. You'd think it would have the same OOO as regular division, but it does not:

?10/2*5
 25 
?10\2*5
 1

[Gamemaster1494]

so since \ is integer division, what is /? just regular old division? even if i did 1/2 or 1\2, would it still show .5?

[Ellis Dee]

/ is actual division. 1/2 = 0.5
\ is integer division, which only returns integers. 1/2 = 0

\ is orders of magnitude faster than / because division is a very expensive operation. You should use \ over / everywhere possible. It doesn't actually do division, but instead simply counts the number of times the denominator goes into the numerator.

Examples:
10 \ 2 = 5
10 \ 3 = 3
10 \ 4 = 2

Test it Yourself.. far easier than waiting for someone to reply..

MsgBox (1 / 2)
MsgBox (1 \ 2)

You also get Remainder division which gives the remainder. you can use the Mod method for this, for example :

8 Mod 7

Will give me 1

and

6 Mod 4

Will give me 2

You should use \ over / everywhere possible.

"May need to" would arguably be more appropriate to say instead - otherwise you may lose precision in many cases like this wich may be crucial:

10 \ 6 = 1
10 / 6 = 1.66666666666667

[Ellis Dee]

Agreed. You can't use it when precision is required. You should use it everywhere else.

Darn. Now i have to go threw and change the signs. Thank god for Find and replace! Thanks everyone! I'll use / from now on. =)
