Talk:Map range

This task was created for one simple reason: I was trying to remember how to do what the C++ example I wrote and provided does. The task description can probably use work. I also know that there are weird scenarios, such as in resampling, where that code doesn't quite work, but I think that's a different problem. (Possibly worth its own task. Given two arrays of N1 and N2 elements, find the corresponding element in N2 for N1.) --Michael Mol 16:17, 25 November 2010 (UTC)

So we're talking about floating-point values? If we are, we can just ignore the nasties with sampling errors since they at least model reals. –Donal Fellows 16:27, 25 November 2010 (UTC)

The particular case I recall occurred at work some time ago when trying to scale up drawing operation coordinates on a raster display. Not quite real life, sadly. If this task should renamed to 'map range of reals' to keep things simple(r), that'd be fine by me. (I wonder what that does to n-dimension and imaginary numbers, where n is greater than 1.) BTW, did you see my note on {{uses from}}? --Michael Mol 16:48, 25 November 2010 (UTC)
