Android Question Int To DIP

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

no
this is error in the compilation

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

what a shame, a beginner's mistake

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().

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.
