Verilog Remainder

When implementing trigonometric functions, taking into account the periodic function, the amount of the heald (argument) required for the remainder operation cycle.

Suppose the function period is T = 2 ^ N, then the remainder operation that is taken directly to the lower N-bit number, namely:

In Case M-bit positive number (sign bit is 0), reg [M-1: 0] data; mod_data = {0, data [N-1: 0]};
