Though negative numbers are naturally represented by 2-compliment cod and will have the uppper bit set to '1'. Supposedly your tes_num is 32 bit, than you can always test test_num [31] for negativity.

Something like this may work: for ( int i=limit; i WebNov 12, 2013 · This is known as a logical shift, since it strictly follows the logical definition of "shifting", that is, moving the existing bits one position towards the LSb. If we shift in the same value as the MSb, we change the value but retain the sign: 0b0110 (6) -> 0b0011 (3) 0b1110 (-2) -> 0b1111 (-1)

One of them selects between the input data and the input data shifted by 1 bit, the next one shifts by 2 bits, the next one by 4, etc. The bits of n are then used as the select inputs for those muxes. Shifting by 64 bits requires 6 levels of 64 bit 2:1 muxes. first original 13 statesWebOct 11, 2014 · Verilog already had >> to mean logical shift in 1985 (taken from Pascal, which is from 1970).
