Re^2: Determining the minimum representable increment/decrement possible?

I'm probably being thick here, but where does nextafter() come from?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice. Not understood.

... where does nextafter() come from? As pryrt noted, it's in math.h - which perl.h already (indirectly) includes. With my MS compiler, I found matches for the string "nextafter" in: `C:\_64\Platform_SDK\Include\crt\float.h C:\_64\Platform_SDK\Include\crt\fpieee.h C:\_64\Platform_SDK\Include\crt\math.h C:\_64\Platform_SDK\src\crt\float.h C:\_64\Platform_SDK\src\crt\fpieee.h` [download] Cheers, Rob	[reply] [d/l]

it looks like it's in math.h -- I didn't know about it until syphilis's post, either... I love how much I learn here. :-)	[reply]

For completeness, `nextafter()` is specified as part of `math.h` in C99 (section 7.12.11.3 in the N1256 draft).	[reply] [d/l] [select]
