| -- These testcases are experimental ('beta' versions), and they -- | |

| -- particular, achieving the same results as the tests here is not -- | |
| -- a guarantee that an implementation complies with any Standard -- | |

| -- 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 | |
