- newer naming allows for less confusing code.
Eg,
max(lower) -> clamp_min(lower)
min(upper) -> clamp_max(upper)
- prefer combined method, for few operations.
Eg,
max(lower) + min(upper) -> clamp_range(lower, upper)
The updated naming also helps avoid some obvious coding errors.
Eg,
Re.min(1200.0);
Re.max(18800.0);
instead of
Re.clamp_range(1200.0, 18800.0);
- can also use implicit conversion of zero_one to MinMax<Type> for
this type of code:
lambda_.clamp_range(zero_one{});
