I think the right check for underflow is: *before* calling
exact_real_truncate
Hello.
I am using real_isfinite to check for overflow conditions. How should
I check for underflow? I have tried different ways but they
contradicted other cases to pass.

If the mathematical result of the arithmetic operation is literally the

Hello.
Should a result like 1.4 be considered as inexact if truncating
(narrowing?) from double to float? (due to loss of trailing bits)
Comments of real_arithmetic says that it returns TRUE if the result is
inexact. There's another function, exact_real_truncate which returns
TRUE if truncation is

Hello.
I have made changes in the patch according to the above corrections.
However, I didn't understand how these following testcases are
supposed to handle. Will you please elaborate some more?

Hi.
This patch includes fadd variants implementation for folding. The
patch bootstraps and survives regression tests on x86_64-linux-gnu.
