SYNTAX ERROR: Only i32 is supported for now

Hello, I encountered this problem surprisingly

SYNTAX ERROR: ./variables.carbon:6: Only i32 is
supported for now: f32

package JetBlack api;

fn Main() -> i32 {
    var policy:i32;

    var f :f32 =5.6; // this line 
    return 0;
}

Why?

It's just a matter of what we've implemented so far; the implementation is incomplete as we were preparing to implement the types as Carbon library types versus C++ code (as is done for i32). See #767.
