Subject: [9front] Missing insnan() in /386/include/ape/math.h?
Reply-To: 9front@9front.org
Precedence: bulk

Hi!
I looks (to me) like ape/math.h for 386 is missing the following two lines:

#define isnan(x) isNaN(x)
#define isinf(x) isInf(x, 0)

They are present in
/{68020|arm|arm64|power|sparc|sparc64|amd64}/include/ape/math.h. It
even looks like the lines are present for 386 in the stock Bell Lab's
distro. Any known reason for this irregularity? isnan() is used by
Netsurf's SVG-library.
