Formatting Numbers

[BGM]

Oh, I am completely bewildered by this.

In my script, when I do math with division, I get numbers in scientific format - with e's in them (I'm writing a calculator app)

610*2.17 = 1.3237000000000000e+003

My code is long and complicated and I'm not sure what I did to get this to happen.
What do I look for, and how do I get it to just give me 2 decimal points?

Now, I have this which I am using to switch back to regular numbers (because I switch to hex in another place)

Code: Select all

ResetNormalFormats:
	if(usedecimalplaces){
		normalfloatformat := "0." . decimalplaces+1 . "g"	;you have to add 1 to the number to display the correct amount of digits
	}else{
		normalfloatformat :=  "0." . maxdecimalplaces+1 . "g"
	}	
	
	;W := W="" ? "0.6g" : "0." . W 
	;SetFormat Integer, %FormI%
	SetFormat Integer, D	;decimal format
	SetFormat FLOAT, %normalfloatformat%
return

why are u appending a "g"?

At one time I thought it would help eliminate the trailing zeros...

So, I've removed the g and the +1 and now it's not doing exponents any more so it's not so horrendous.
Then I use rtrim() to remove trailing zeros.

Code: Select all

ResetNormalFormats(){
	global
	if(usedecimalplaces){
		normalfloatformat := "0." . decimalplaces
	}else{
		normalfloatformat :=  "0." . maxdecimalplaces
	}	
	
	SetFormat Integer, %FormI%
	SetFormat Integer, D	;decimal format
	SetFormat FLOAT, %normalfloatformat%
}

Then in my code, I do this:

Code: Select all

ResetNormalFormats()
y := rtrim(y,0)

So, with this format for the float, it always gives me trailing zeros, and the setformat is undoing my rtrim due to it's global nature and the different threads.
Also, you can use setformat to format both decimals AND floats simultaneously without having to know ahead of time what kind of value you have.

Is there a way to change the parameter for setformat FLOAT so that there are no trailing zeros after the decimal?

- SetFormat isn't available in AutoHotkey v2, so you could try getting used to the Format function instead. See FORMAT FUNCTION EXAMPLES, here:

Code: Select all

MsgBox, % formatFloatTrimZero(610 * 2.17)
MsgBox, % formatFloatTrimZero(610 * 2.171231234122342352623)
MsgBox, % formatFloatTrimZero(610 * 2.171231234122342352623, 10)
MsgBox, % formatFloatTrimZero(610 * 2)

formatFloatTrimZero(floatNum, decimalPlace := 6) {
	if floatNum is integer
		throw Exception("Illegal argument passed to function " . A_ThisFunc . "().`nSpecifically: Integer (" . floatNum . ")")

	return RTrim(Format("{:0." . decimalPlace . "f}", floatNum), "0")
}

Thanks y'all, but my problem is that SetFormat has a global effect; my script is a bit old (from before it was deprecated), and I'm not sure how to change things so that I could work on each variable. Maybe someone could take a look at my script and give me some advice?

I'll leave these links here for awhile; I don't really want them public, but it's okay for awhile, I think.

This is the math part:

This is the part where the math function is called, so you can see how it is returned to the GUI.

Problem is that SetFormat in the math part doesn't affect the settings in the GUI part.
