This is a tentative fix for the issue described at https://bugs.python.org/issue38992. One of the tests
for
math.fsum
was failing on a cross-compiled Python, due to two different values of a constant (1.7**1000
) being used.The change in this PR ensures that each power of
1.7
used in thefsum
test is only computed once, so that there's no danger of using two different values of1.7**1000
.https://bugs.python.org/issue38992
