In general, this is why LIA-2 (Language Independent Arithmetic, part 2, "Elementary numerical functions", ISO/IEC 10967-2:2001) [. . .] This sounds like a very interesting standard. I am constantly annoyed by ISO's attempts to hide their standards; one might wonder what the purpose is of having unavailable "standards". Is the content available somewhere?
You have to pay for it. I too find this exceedingly annoying, but it stems from the notion that any body that provides something useful should make money from it. The standards bodies (ISO, BS in particular) are expected to recoup costs by selling the documents. That this makes the standards less effective doesn't seem to matter. I don't know what could be done to persuade them to behave differently.
