Expand description

Creates a DecInterval from f64 bounds or from a decorated interval literal.

There are two variants of the macro:

  • dec_interval!(a, b)

    Creates a decorated interval $[a, b]$ with the strongest decoration. The condition $a ≀ b ∧ a < +∞ ∧ b > -∞$ must be held.

    a and b must be f64 values.

  • dec_interval!(s)

    Creates a decorated interval from a decorated interval literal. s must be a string slice (&str).

The result is a Result<DecInterval>.

If the construction is invalid, an Err value with IntervalErrorKind::UndefinedOperation is returned. If it fails to determine whether the construction is valid or not, IntervalErrorKind::PossiblyUndefinedOperation is returned.

For creating a constant, the macro const_dec_interval! should be preferred over this one.
