Relational operators

Relational operators are used to relate or compare two values. The result of the comparison is a value of type Bool.

• == is equal to
• != is not equal to
• <= is less than or equal to
• >= is greater than or equal to
• < is less than (must be enclosed in whitespace)
• > is greater than (must be enclosed in whitespace)

Some examples:

let b : Bool = 2 > 3;

let c : Bool = (2 : Int) >= 2;

let d : Bool = 1.61 == 1.61;

In the first line we compared two Nat values. The result is the value false of type Bool.

Notice how we type annotated the value itself in the second line, therefore telling Motoko that we are now comparing two Int values. The result is the value true of type Bool.

In the last line we compared two Float values. The result is the value true of type Bool.
