why the same division has different result?

[clould365]

There are two different expression
1.reg baud_rate=3;
wire [15:0] one_bit_clock_nums;
assign one_bit_clock_nums =2083/(2^baud_rate);
2.assign one_bit_clock_nums =2083/8;

In ModelSim,
the result are
1.2083
2.260

what's the reason?
BTW,Is division Synthesizable?

 

[permute]

2^3 = 1

like in C, "^" is "xor".

Indeed. You probably think 2^a is taking the a power of 2. Which it isn't. As permute said the ^ operator is XOR.

If you want 2 to the power of something, you can use (2 << a). Also very much like C.

Sorry ,I know my fault,so stupid I am
