Content
This is a near duplicate of issue7281. Most likely, copysign is behaving correctly, and it's already the float conversion that errs. For struct.pack('d', float('nan')), I get '\x00\x00\x00\x00\x00\x00\xf8\xff'; for -nan, I get '\x00\x00\x00\x00\x00\x00\xf8\x7f'; ISTM that this has the sign bits switched.
