Android Question Int To DIP

[LordZenzo]

this simple operation generates an error in the compilation

 LS1.Padding=Array (6.7%x ,0dip,0dip,0dip) [\CODE]

in the forum I found this solution
[CODE]
Sub IntToDIP(Integer As Int) As Int 
   Dim DIP As Int
   DIP = Integer * 1dip
   Return DIP
End Sub
[\CODE]

To have greater precision and avoid the rounding of 1Dip, Erel suggested to work 100dip / 100.
The error is perhaps generated by the fact that you use reserved KeyWords

Sub IntToDIP(Value As Int) As float
    Return Value*(100dip/100)
End Sub

no
this is error in the compilation

LS1.Padding=Array(IntToDIP(4%x),0dip,0dip,0dip)
javac 1.8.0_131

Try it

Dim V as Int =IntToDIP(4%x)
LS1.Padding=Array(V,0dip,0dip,0dip)

 

[LucaMs]

LS1.Padding=Array (6.7%x ,0dip,0dip,0dip)

LS1.Padding = Array As Int (6.7%x ,0dip,0dip,0dip)

 

[LordZenzo]

LS1.Padding = Array As Int (6.7%x ,0dip,0dip,0dip)

what a shame, a beginner's mistake

 

[emexes]

Sub IntToDIP(Integer As Int) As Int

Super-minor point, but... I think this function converts DIPs to P(ixel)s, ie, the opposite of its name.

Perhaps rename it to DIPToPixel() or PixelFromDIP().

 

[emexes]

To have greater precision and avoid the rounding of 1Dip, Erel suggested to work 100dip / 100.

Whilst down in the mud of pedant detail here...

Since DIP's are defined as 160 per inch, I've been using 160DIP / 160 as the conversion factor, which likely cancels out an integer rounding based on the DIP suffix probably being equivalent to the integer operations: * DevicePPI / 160.

On the one hand, we're only talking about being one pixel out; on the other hand, sometimes one pixel errors stand out like a star in the night sky, especially if there's a line of them.
