Comparison and equality

Comparison

We can compare values using C style comparison operators:

less < than
lessThan <= orEqual
greater > than
greaterThan >= orEqual

Equality

Of same types

We can test two values for equality:

Example

1 == 2 //false
"2" is "2" //true

And for inequality:

Example

1 not 2 //true
"2" != "2" //false

Of different types

We can test different types for equality (which will, by default, always evaluate to false).

Example

314 == "pi" // false
123 is "123" // false

And for inequality (which will, by default, always evaluate to true).

Example

314 not "pi" // true
123 != "123" // true

Checking type

In Hades, the equality operator also works as a typecheck. You can check any value against a proto or type. The operation will return true if the value is an instance of said proto.

Example

123 == int // true

var v = VideoStream("bigbuckbunny.mp4")
v is Vector // false
