-- --
-- These testcases are experimental ('beta' versions), and they --
-- may contain errors. They are offered on an as-is basis. In --
-- particular, achieving the same results as the tests here is not --
-- a guarantee that an implementation complies with any Standard --
-- or specification. The tests are not exhaustive. --

-- These tests comprese three parts:
-- 1. Sanity checks and other three-operand tests (especially those
-- where the fused operation makes a difference)
-- 2. Multiply tests (third operand is neutral zero [0E+emax])
-- 3. Addition tests (first operand is 1)
-- The multiply and addition tests are extensive because FMA may have
-- its own dedicated multiplication or addition routine(s), and they
-- also inherently check the left-to-right properties.
-- Sanity checks
