```
public static int encode(float x)
```
    Quantizes double (64 bit) values into 32 bits
    
    Parameters:
    
    x - cartesian value
    
    Returns:
    
    encoded value as a 32-bit int
    
    Throws:
    
    IllegalArgumentException - if value is out of bounds
  - decode
```
public static float decode(int encoded)
```
    Turns quantized value from encode(float) back into a double.
    
    Parameters:
    
    encoded - encoded value: 32-bit quantized value.
    
    Returns:
    
    decoded value value.
  - decode
```
public static float decode(byte[] src,
                           int offset)
```
    Turns quantized value from byte array back into a double.
    
    Parameters:
    
    src - byte array containing 4 bytes to decode at offset
    
    offset - offset into src to decode from.
    
    Returns:
    
    decoded value.
