The number 49 in Roman numerals is XLIX and the number 99 in Roman numerals is XCIX
In todays modern notation of Roman numerals they represent 99
99
99+1056 = 1155 or MCLV in Roman numerals Today we write out 99 in Roman numerals as XCIX but the Romans themselves would have probably wrote it out simply as IC (-1+100 = 99)
99 = IC (-1+100) But today's conversion of 99 into Roman numerals is XCIX However, the Romans themselves would have probably wrote out the number 99 as LXXXXVIIII which then can be simplified to IC

99
In today' notation of Roman numerals it stands for 99 but during the Roman era the equivalent of 99 in Roman numerals would have probably been written out simply as IC (100-1 = 99)
Nowadays we would convert 99 into Roman numerals as XCIX But the ancient Romans probably chose the simpler version of IC
Today's conventional way of writing 99 into Roman numerals is XCIX. However the Romans themselves would have probably calculated 99 on a abacus counting device as LXXXXVIIII and then wrote it out as IC (-1+100 =99)
XCIX - XIX = LXXX
If you mean IC = 100-1 in Roman numerals then its full form is LXXXXVIIII = 99 Note that in todays modern configuration of Roman numerals 99 is now considered to be XCIX
because it's too complicated to calculate with roman numerals. eg 11 * 9 = 99 => XI * IX = XCIX
