Cast int to float in F#

Question

Learning F#, the syntax is still quite foreign to me. How do I cast this integer to float?

let add x y =     x + y  let j = 2 add 1.1 j 

In C# Float + int= Float

float j = 1.1f + 5; 

Answer 1

EDIT: misread the question...

I'm pretty sure that the float() function would do the job:

add 1.1 (float 2) 

Answer 2

First, the function you specified has type int->int->int which means it takes 2 ints and returns an int. If you want it to use floats you need to specify the type of one of the arguments:

let add (x : float) y = x + y //add : float->float->float 

As others have mentioned, you can cast to a float using the float() function:

float 2 //2 : float 

If you are using numeric literals like in your example, you can just use 2.0 instead of 2 which has the float type.

add 1.1 2.0
