Create an i32 Val.t

Sourceval of_i64 : int64 -> t

Create an i64 Val

Sourceval of_f32 : float -> t

Create an f32 Val

Sourceval of_f64 : float -> t

Create an f64 Val

Sourceval to_i32 : t -> int32 option

Get an int32 from Val if the type matches

Sourceval to_i64 : t -> int64 option

Get an int64 from Val if the type matches

Sourceval to_f32 : t -> float option

Get a f32 from Val if the type matches

Sourceval to_f64 : t -> float option

Get an f64 from Val if the type matches

Sourceval to_i32_exn : t -> int32

Same as to_i32 but raises Invalid_argument if the types don't match
