Re: [Boost-users] [Units] Un-scaling dimensionless value

For the life of me I can't figure out where the actual multiplication of the value occurs. Boost Units is very clever template magic, but I doubt anyone could maintain the thing without weeks of studying the design.... On Mon, Feb 17, 2014 at 9:48 AM, Lindley French wrote:

What's the best way to access the current scaling of a dimensionless value? Maybe I can back it out myself rather than relying on type conversion to do it.

Hmm. Ideally, I'd love it if floating point conversions were only used when the value type is floating point; the rest of the time, an integer conversion or static assert if necessary could be used. But thanks for the insight into the current behavior.

Given that I wrote the code, yes I'm certain. The values can be too large to fit in an integer type (even long long).
