[Trigger] Real Value Bugged

[kirimura123]

So i was making a map, and i use real value to roll a number between 0.01 - 0.03 i make 3 different effect each abilities has a trigger like this:
Event - a unit starts the effect of ability
Condition - Ability being cast equal to (Dice Roll)
Action - Set (Roll) = roll a random number between 0.01 - 0.03
If (Roll) equal to 0.01 then blah blah blah the effect and keep repeating like that till 0.03

the problem is everytime i cast the ability it always get 0.03 it even got 2 effect at the same time so i tried removing the 0.03 and everytime i cast sometimes theres no effect sometimes there's an effect. how do i fix this? please help!

Real values can also be 0.015347 for example.

Use integers instead they are discrete.

Do you know that between 0.01 and 0.03 are, like, infinity amount of numbers? Guess you're looking for random number between integers 1 and 3

Warcraft 3 only lets you put in two digits for real numbers but that's just an interface issue, not an actual limit of the data type. You can achieve 0.015 in JASS or by using math in GUI.

Real equality test has a large epsilon error to it. The inequality comparator does correct floating point comparisons. This means that there exist real values that are both equal and not equal to each other.

For chance mechanics I recommend using random integer values instead. They are much easier to define and think about.

@kirimura123

0.01 is equal (epsilon) and not equal (actual) to 0.0102

You can do it like this, though:

Real(Integer(Random real number between 1 and 3)) / 100

 

[MasterBlaster]

Real(Integer(Random real number between 1 and 3)) / 100

So, convert Real to Integer and then to Real again?

I think it's better to just go with an integer for this one
Or do something like this if the OP really wants a Real - Real(Random integer number between 1 and 3)/100.

^^ Oops, my mistake. It should be:

Real(Random integer between 1 and 3)/100
