My company is using SQLite. We need to do some formatting to the data before posting it to a webpage. What we want to do are simplier tasks such as zero padding, limiting placess to the right of the decimal etc. We are thinkng about writing C Extensions to SQLite to do this. But I was wonde

2010-11-04 Thread Joshua Grauman
Hello all, The simple question is, is there any way in SQLite to format (left align) integers? So for example I want to print 1 as 1, 23 as 00023, 102 as 00102, etc. The real issue I'm trying to solve is a sorting one. I run some SQL which takes some integers and creates a column for sorti

I had an application which had 5 cm meter accuracy and needed to get points with 1 meter for example. I ended up writing my own search method. I'm sure others are trying to do similar. The patch I submitted doesn't change the original code at all unless you enable the RTREE_DOUBLE. So it s

If you're trying to get more than 6 or 7 significant digits, yes And if you're dealing with lat/lon 1 degree = 69.04 miles or 364531.2 feet So if youi're trying to get sub-foot accuracy/precision you need the digits. Not quite so important for the RTree I would think as it is for the actua

Are you sure that double precision in the RTree is necessary for your purposes? Here is a table of floating point precision at various values: The 'flip' values are the 'org' values with the lowest bit flipped. org flip (delta) 0.01 0.01 ( 0.0
