The block decomposes the input data to up to four (integer) values composed from defined range of bits.

The block decomposes the input data according to the low and high parameters. For example, to evaluate the first 4 bits as a value ranged from 0 to 15, fill in low as [1,0,0,0] and high as [4,0,0,0]: the low bit is 1, the high bit is 4. The resulting value will be in the first element of the output array. bs is the sign of the input data. The displayed range may be 2 to 32 bits.

Input vector decomposition with parameters low = [1,5,1,13] and high = [4,8,8,16]. The first value is composed from bits 1 to 4, the second value is composed from bits 5 to 8, third value from bits 1 to 8, and fourth value from bits 13 to 16 of the input value dint1.
