Comparing floating point numbers


If we had integers I can compare them like so

let a = 12 < 21

I seem to missunderstand how to perform comparison for floats as the code below gives me an error

let b = 1.22 <. 2.11

How is comparison done for floats ?


Comparison operators are polymorphic in OCaml/ReasonML, so you can do let b = 1.22 < 2.11;

The general type of all comparison operators is 'a => 'a => bool, that means you can compare any two values for equality or inequality as long as they have the same type. See for details.
