Float. The specific meaning of the return value of floattorawintbits is to convert float into byte array

1 Code

int i = Float.floatToRawIntBits(9f);

2 explain

What is returned is the decimal number of the floating-point number of the value .

3 When to use this

We need to turn a two-dimensional array into a picture , Generally used byte transformation , That is to say, first put the float Use this for the value of Float.floatToRawIntBits(9f)
To int,
after

 public static byte[] getBytes(int      Float.floatToRawIntBits(x)) {
    
        return new byte[] {
     (byte) x, (byte) (x >>> 8), (byte) (x >>> 16),
                (byte) (x >>> 24) };
    }

such as Incoming x by 1.0f
Output is

[0, 0, -128, 63]

The above will realize float To byte Array
