Method Details

encodeExponent9Bits

public static int encodeExponent9Bits(int exponent11)

Encodes a double exponent into 9 bits if possible. Handles special cases for zero/subnormal and NaN/Infinity.

Parameters:

exponent11 - The original 11-bit exponent.

Returns:

Encoded 9-bit exponent as int (0-511), or -1 if not encodable.

decodeExponent9Bits

public static int decodeExponent9Bits(int encoded)

Decodes a 9-bit exponent back to the original 11-bit exponent.

Parameters:

encoded - 9-bit encoded exponent

Returns:

11-bit biased exponent or special values for reserved patterns

decodeExponent10Bits

@Deprecated
public static int decodeExponent10Bits(int encoded)

Deprecated.

Use decodeExponent9Bits(int).
