therefore, sum([1e+308, 1e-308, 1e+308]) returns 1e+308 while
sum([1e+308, 1e+308, 1e-308]) raises an OverflowError due to the
overflow of the first partial sum.
Note 3: Aggressively optimizing compilers can potentially eliminate the
residual values needed for accurate summation. For instance, the statements
"hi = x + y; lo = y - (hi - x);" could be mis-transformed to
"hi = x + y; lo = 0.0;" which defeats the computation of residuals.
Note 3: The itermediate values lo, yr, and hi are declared volatile so
aggressive compilers won't algebraicly reduce lo to always be exactly 0.0.
Also, the volatile declaration forces the values to be stored in memory as
regular doubles instead of extended long precision (80-bit) values. This
prevents double rounding because any addition or substraction of two doubles
can be resolved exactly into double-sized hi and lo values. As long as the
hi value gets forced into a double before yr and lo are computed, the extra
bits in downstream extended precision operations (x87 for example) will be
exactly zero and therefore can be losslessly stored back into a double,
thereby preventing double rounding.
Note 4: A similar implementation is in Modules/cmathmodule.c.
Be sure to update both when making changes.
