00036  * This file include the declaration of common tables.
00037  * Most of them are used for activation functions 
00038  *
00039  * Assumption:
00040  * Unified table: input is 3.x format, i.e, range of [-8, 8)
00041  * sigmoid(8) = 0.9996646498695336
00042  * tanh(8) = 0.9999997749296758
00043  * The accuracy here should be good enough
00044  *
00045  * 2-stage HL table: 
00046  *
00047  * The entire input range is divided into two parts:
00048  *
00049  * Low range table: 0x000x xxxx or 0x111x xxxx 
00050  * table entry will be the binary number excluding the first
00051  * two digits, i.e., 0x0x xxxx or 0x1x xxxx
00052  * 
00053  *
00054  *
00055  * High range table 0x0010 0000 -- 0x0111 1111
00056  *                  0x1000 0000 -- 0x1101 1111
00057  * 
00058  * For positive numbers, table entry will be
00059  * 0x0010 0000 -- 0x0111 1111 minus 0x0010 0000
00060  * i.e., 0x0000 0000 - 0x0101 11111
00061  *
00062  * same thing for the negative numbers, table entry will be
00063  * 0x1000 0000 -- 0x1101 1111 minux 0x0010 0000
00064  * i.e., 0x0110 0000 - 0x1011 1111
