Platform-dependent. 1.775 isn't exactly representable regardless, but
whether exactly-half-way numbers that are exactly representable round
up or truncate varies across

Hello,
What is the proper way to limit the results of division to only a few
spaces after the decimal? I don't need rocket-science like precision.
Here's an example:
1.775 is as exact as I need to be and normally, 1.70 will do.
Thank you,
