Initialising an int64 variable

I tried initializing an int64 variable in the following way : 

let k:int64 = 4000000000;;

However I got the following error message : 

Error: Integer literal exceeds the range of representable integers of type int

How do I intialise k to a value of 4 billion? Thanks.

You should use L specifier to indicate an int64 literal:

let k = 4000000000L;;

Alternatively, since the number exceeds the range of int32, you can convert it from float:

let k = Int64.of_float 4000000000.;;
