Trunc(x)/Franc(x) in lua

[jsmorley]

To be clear, they are global in the context of that Script measure.

Also note that you can't use a variable in Function1() if it is defined in Function2() and Function2 has not been called yet.

That isn't exactly what he asked for though. He asked that 23.12 be turned into 23 and 12, not 23 and 0.12. math.floor() is fine for getting the integer part, but not so good for the decimal part.

Oops!!! I missed this small detail I think, but you're perfectly right. Sorry.

If you do in fact want the integer portion as an integer, and the decimal portion as a decimal, there is one simple math function...
Int, Dec = math.modf(myNum)

I didn't know about the math.modf function. It can be useful I think in some cases. Good to know about it.

Well, to be fair, the subject of his post was entirely at conflict with what he asked for in the body of the post.

fract(x) in fact returns the decimal portion of a number as a decimal, so if you go by his post subject, you are right, but in the body he seems to indicate that he wants the decimal portion returned as an integer, which is a horse of a different color.

All variables are global in Lua unless you specify local on them.

Sorry if I wasn't clear enough, what I'm asking is if I define a variable to be local in a function, will a function called by the first one be able to use that variable?

No, not if you define it as "local". You would then have to pass the value as a parameter to the second function.

Right. But it was my inattention (sorry for this), because I know I read he wants the decimal part as integer, but finally when I posted my reply, I forgot about this.
Anyway doesn't matter too much, because kyriakos876 wrote in the meantime that the decimal part as decimal is ok.

He just likes to make extra work for us by not be at all clear and precise about what he is trying to do... The latest "local" question is another example of this...

I don't comment...

Alright cool. Got it.

I agree, the title might have been a little bit misleading I must say,

And if there's one equivalent to the Franc(x) but not exactly... I want as the end result this:

But yea, mainly because I didn't know how else I to put it, I used this to better describe it.

Yup, I'm bad at explaining what I want sometimes... I'm trying to make it simple but it turns out complicated.
Pardon me

Here is how it works:

If you have a skin like this:

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1
AccurateText=1

[Lua]
Measure=Script
ScriptFile=Test.lua
Disabled=1

[MeterResult]
Meter=String
FontSize=11
FontWeight=400
FontColor=255,255,255,255
SolidColor=47,47,47,255
Padding=5,5,5,5
AntiAlias=1
DynamicVariables=1
Text=[&Lua:Function1()]

And Lua like this:

Code: Select all

function Function1()

		myVar1 = 5
		myVar2 = Function2()
		
		return myVar2
		
end

function Function2()

	return 20 + myVar1

end

It works fine and returns "25" to the skin.

If you have Lua like this:

Code: Select all

function Function1()

		local myVar1 = 5
		myVar2 = Function2()
		
		return myVar2
		
end

function Function2()

	return 20 + myVar1

end

That is an error, as myVar1 does not exist in the context of Function2().

You would have to:

Code: Select all

function Function1()

		local myVar1 = 5
		myVar2 = Function2(myVar1)
		
		return myVar2
		
end

function Function2(arg)

	return 20 + arg

end

In order to pass the "local" value of myVar1 to Function2(arg)
