[Example

: *end example*

]is_modulo is false for signed integer types ([basic.fundamental])
unless an implementation, as an extension to this document,
defines signed integer overflow to wrap.

— ```
static constexpr bool traps;
```

```
static constexpr bool tinyness_before;
```

```
static constexpr float_round_style round_style;
```

lowest() is necessary because not all
floating-point representations have a smallest (most negative) value that is
the negative of the largest (most positive) finite value.
