Re: [Pharo-users] Set Rounding mode for IEEE floating point operations

Hi Henry,

[...] it might be possible to try to do this with FFI only?

If I understand you correctly, I could use FFI to call an external lib to perform the actual computation according to the rounding mode, right? In this case I'd be worry about the performance impact of many FFI calls.

For the same reason, I hope you intend roundByMethodXWhile: to be a mandatory API, forgetting to set the mode back when done (or, never getting there due to errors, etc) is an area best left unexplored ;)

I used roundByMethodXWhile: aBlock just to convey the idea that an API could work "local" and ensures resetting the rounding mode afterwards. =) Best, Steffen
