Parameters
a
, b
, 'c': floating arguments.Return value
Computes elementwise a triplet of values [f, r1, r2]
such that:
f
is fma(a, x, y)
\f$ a\otimes x\oplus y = r1\oplus r2\oplus r3\f$ exactly ! *
\( |r1 \oplus r2| \le ulp(r1)/2\)\f$ |r2| \le ulp(r2)/2\f$
where \(\oplus\) (resp. \(\otimes\)) adds (resp. multiplies) its two parameters with infinite precision.
