[New-bugs-announce] [issue14381] Intern certain integral floats for memory savings and performance

[Kristján Valur Jónsson]

New submission from Kristján Valur Jónsson <kristjan at ccpgames.com>:

Michael Foord reminded me of this issue recently.  It was discussed on pydev a few years back and met with limited enthusiasm.  I speak from experience in live production with EVE that this simple change saved us a lot of memory.  Integral floating point numbers are surprisingly common, falling out of mathematical operations and when reading tabular data.  0.0 and 1.0 in particular.
