Yes, I'm on a quest for the arc! Arctan that is! Yeah, isn't that exciting! Anyway, MMF's maths seems pretty advanced but there does't seem to be an arcsin, arccos or arctan function, which is a shame because they're really a lot more useful than sin, cos and tan. However, I thought MMF doesn't even do decimals, which kinda makes trigonometric functions useless anyway because you'll always get 0 as it rounds down. Am I wrong about this? No, I'm never wrong, but I'd like to be told that I was "misguided" on this occasion. So if you have any idea what I'm saying, and know the answer to my problems, please answer... here.

Well you are misguided, you can acess the arc functions in the expression editor underneath the special conditions and MMF can use decimals but I forgot which function it is. Instead of using decimals you could always just multiply the value of the sin/cos for example:

cos(x) * 100

cant you put " 1.5/1.5* " at the beginning of your expression, or something?

You can force MMF to use decimals by adding 0.0 to both the numerator and denominator of a division, ie:
((0.0 + Value A of Thing)/(0.0 + Value B of Thing))

You can just times it by 1.0, for example:

X * 1.0

Will automatically promote X to a float.

However the Arctan function in MMF always returns a float anyway, so there is no need to do anything in order to convert it. For example, create a counter and have it display the result of ATan(5), you'll see that it comes up as 1.3734 without needing to do any processing to convert it to a float.
