tan11.25用verilog语句编写

同样地，以下是一个可以计算tan(11.25)的Verilog模块：

module tan_11_25(output reg [31:0] result);
reg [31:0] pi, rad, angle;
reg [31:0] numerator, denominator, fraction;
integer i;

// Convert 11.25 degrees to radians
pi = 32'h3243F6A9;
rad = (pi * 11.25) / 180;

// Calculate the numerator and denominator of the Taylor series
numerator = rad;
denominator = 1;
fraction = numerator / denominator;
result = fraction;

// Calculate the Taylor series approximation of tan(11.25)
for (i = 1; i <= 10; i = i + 2) begin
  numerator = -numerator * rad * rad;
  denominator = denominator * (i + 1) * i;
  fraction = numerator / denominator;
  result = result + fraction;
end

endmodule

此代码与上一个示例非常相似，只是将22.5度更改为11.25度。请注意，这种方法只能提供近似值，并且可能存在舍入误差。
