y = a bitset b
a bitset b sets the bth bit of a. Both a and b are treated as 32-bit (4-byte) integer values, so an eventual fraction will be ignored.
In 20-sim, all bitwise function arguments are treated as 32-bit integers. Thus the binary representation of 30 (ignoring leading zeroes) is equal to 11110 as shown in the figure below. The operation 30 bitset 1 sets the last bit of 11110 to one which gives 11111. This binary value corresponds with a decimal value of 31.
a and b must be integers.
