description: Rounding for roundingIncrement option
info: |
ToTemporalRoundingIncrement ( _normalizedOptions_ )
1. Let _increment_ be ? GetOption(_normalizedOptions_, *"roundingIncrement"*, *"number"*, *undefined*, *1*<sub>𝔽</sub>).
2. If _increment_ is not finite, throw a *RangeError* exception.
3. Let _integerIncrement_ be truncate(ℝ(_increment_)).
4. If _integerIncrement_ < 1 or _integerIncrement_ > 10<sup>9</sup>, throw a *RangeError* exception.
5. Return _integerIncrement_.
