高分求加密算法

Question

请加密算法，明文与密文如下：加密密文             明文
FPOCPFADDP =2.800
DPOCFFADBP =4.210
DPOCCF         =4.500
CP         =5.000
JOIDDF         =0.840
GPOCDFFDGP =1.451
GP         =1.000
JOBDHFFD         =0.105
JODD         =0.300
JOADEF         =0.030
JOGD         =0.600
JOCD         =0.200
JODDEF         =0.330
JOEDCFHD          =0.457
JOED         =0.400
JOADCF         =0.050
JODD         =0.300
请各位大侠给出其加密算法，谢谢

Answer 1

目测一下能看出来的是
前4字符 是 G-A 的 对应 1-7, 后面 "POC" 是 "."
前面是 JO 的代表 "0." 后面一位 从 AD-ID 代表 0-8

Answer 2

GP = 1 FP = 2 EP = 3 ... 
JO = 0. 
AD = 0.0 BD = 0.1 CD = 0.2 DD = 0.3 ED = 0.4 FD = 0.5 ...
BF = 0.00 CF = 0.01 DF = 0.02 EF = 0.03 DF = 0.04 ...
AD = 0.000 BD = 0.001 CD = 0.002 DD = 0.003 ED = 0.004 FD = 0.005 ...
