This is another face of "what do do with float"
Just because your default context has n digits of precision
doesn't mean that all your input will.
If my input has 2.4000 (but the extra zeros were measured)
then I want to keep that information.
If my input has 2.4 (and I didn't measure beyond those digits)
I want to know that for error analysis.
If my input has 1.1 (only measured to two digits) but my
context is 25, I don't want to assume that the machine's
float-rounding is correct; the fairest "I don't know"
estimate is still zero, even out to digit 100.
