Multiple comparison operators used together are chained, as if connected via the && operator. This can be useful for readable and mathematically concise comparison chains, such as # same as 0 < i && i <= length(A) isinbounds(A, i) = 0 < i ≤ length(A) # same as Set...

We will look at how to implement custom comparisons by implementing a custom type, ordinal numbers. To simplify the implementation, we will focus on a small subset of these numbers: all ordinal numbers up to but not including ε₀. Our implementation is focused on simplicity, not speed; however, the i...

Julia supports a very large set of comparison operators. These include All of the following unicode sequences: > < >= ≥ <= ≤ == === ≡ != ≠ !== ≢ ∈ ∉ ∋ ∌ ⊆ ⊈ ⊂ ⊄ ⊊ ∝ ∊ ∍ ∥ ∦ ∷ ∺ ∻ ∽ ∾ ≁ ≃ ≄ ≅ ≆ ≇ ≈ ≉ ≊ ≋ ≌ ≍ ≎ ≐ ≑ ≒ ≓ ≔ ≕ ≖ ≗ ≘ ≙ ≚ ≛ ≜ ≝ ≞ ≟ ≣ ≦ ≧ ≨ ≩ ≪ ≫ ≬ ≭ ≮ ≯ ≰ ≱ ≲ ≳ ≴ ≵ ≶ ≷ ≸ ≹ ≺ ...

There are three equality operators: ==, ===, and isequal. (The last is not really an operator, but it is a function and all operators are functions.) When to use == == is value equality. It returns true when two objects represent, in their present state, the same value. For instance, it is obviou...
