Real value constants have width 1
...
Real value constants have width 1 in Icarus Verilog. This is not
the same as the output from $bitstoreal, which is *not* a real
valued expression but a logic vector that losslessly carries the
real value.
Also remove unused CVS markings.

Make sure parameter expressions are evaluated losslessly, as if
the l-value is unsigned and thus virtually infinite.
