 * @brief tables for various activation functions
35 
 *
36 
 * This file include the declaration of common tables.
37 
 * Most of them are used for activation functions
38 
 *
39 
 * Assumption:
40 
 * Unified table: input is 3.x format, i.e, range of [-8, 8)
41 
 * sigmoid(8) = 0.9996646498695336
42 
 * tanh(8) = 0.9999997749296758
43 
 * The accuracy here should be good enough
44 
 *
45 
 * 2-stage HL table:
46 
 *
47 
 * The entire input range is divided into two parts:
48 
 *
49 
 * Low range table: 0x000x xxxx or 0x111x xxxx
50 
 * table entry will be the binary number excluding the first
51 
 * two digits, i.e., 0x0x xxxx or 0x1x xxxx
52 
 *
53 
 *
54 
 *
55 
 * High range table 0x0010 0000 -- 0x0111 1111
56 
 *                  0x1000 0000 -- 0x1101 1111
57 
 *
58 
 * For positive numbers, table entry will be
59 
 * 0x0010 0000 -- 0x0111 1111 minus 0x0010 0000
60 
 * i.e., 0x0000 0000 - 0x0101 11111
61 
 *
62 
 * same thing for the negative numbers, table entry will be
63 
 * 0x1000 0000 -- 0x1101 1111 minux 0x0010 0000
64 
 * i.e., 0x0110 0000 - 0x1011 1111
