roman2integer

@Opt
public static final @Opt Integer roman2integer(MessageReceiver<SimpleMessage<?>> msg,
 String s,
 boolean lowercasesupported,
 boolean uppercasesupported,
 boolean subtractiveformat_directNeighbour,
 boolean subtractiveformat_fartherNeighbour)

Public and Central Service Access Point to convert a string. Supports string in all uppercase or all lowercase. Does not support MIXED subtractive and additive (like "CCCCIV").
The subtractive digit must be a power of ten, so VL, VC, VD, VM, LD and LM are not supported. (Use XLV, XCV, XDV, XMV, CDL and CML instead.)

Parameters:

msg - Message Receiver for error messages

s - the string to convert

lowercasesupported - whether the input may be in lower case only

uppercasesupported - whether the input may be in upper case only

subtractiveformat_directNeighbour - Whether the immediately smaller digit left of a digit means subtraction

subtractiveformat_fartherNeighbour - Whether ANY smaller digit left of a digit means subtraction

Returns:

null in case of error (after sending error message)

int2roman

@Opt
public static @Opt String int2roman(int num,
 boolean uppercase)

Public and Central Service Access Point. Delivers subtractive way of writing (IV, not IIII). MAXIMUM is currently MMMCMXCIX = 3999

Parameters:

num - the number to convert.

uppercase - whether to return in uppercase, not lowercase.

Returns:

the converted string, or null if limit 3999 is exceeded.
