# NaN-testing.
#
# The usual method (x != x) doesn't work.
# Python forces all comparisons thru a 3-outcome cmp protocol; unordered
# isn't a possible outcome. The float cmp outcome is essentially defined
# by this C expression (combining some cross-module implementation
# details, and where px and py are pointers to C double):
# px == py ? 0 : *px < *py ? -1 : *px > *py ? 1 : 0
# Comparing x to itself thus always yields 0 by the first clause, and so
# x != x is never true.
# If px and py point to distinct NaN objects, a strange thing happens:
# 1. On scrupulous 754 implementations, *px < *py returns false, and so
# does *px > *py. Python therefore returns 0, i.e. "equal"!
# 2. On Pentium HW, an unordered outcome sets an otherwise-impossible
# combination of condition codes, including both the "less than" and
# "equal to" flags. Microsoft C generates naive code that accepts
# the "less than" flag at face value, and so the *px < *py clause
# returns true, and Python returns -1, i.e. "not equal".
# So with a proper C 754 implementation Python returns the wrong result,
# and under MS's improper 754 implementation Python yields the right
# result -- both by accident. It's unclear who should be shot <wink>.
#
# Anyway, the point of all that was to convince you it's tricky getting
# the right answer in a portable way!
def isnan(x):
"""x -> true iff x is a NaN."""
# multiply by 1.0 to create a distinct object (x < x *always*
# false in Python, due to object identity forcing equality)
if x * 1.0 < x:
# it's a NaN and this is MS C on a Pentium
return 1
# Else it's non-NaN, or NaN on a non-MS+Pentium combo.
# If it's non-NaN, then x == 1.0 and x == 2.0 can't both be true,
# so we return false. If it is NaN, then assuming a good 754 C
# implementation Python maps both unordered outcomes to true.
