  int cc = aa% BB;
  int dd = aa/bb;

Output results:

3

23

%: Take the remainder

/: Divide division to divide the number of parts

(The difference with MATLAB code)

  Double AA = 24.4;
  Double bb = 3.2;
  Double cc = aa/bb;
  cout << "AA  bb cc:" << aa << "  " << bb << "  " << cc <<endl;

  Double A = 24.4;
  int b = 3;
  Double C = A/b;
  cout << "a  b C:" << a << "  " << b << "  " << c << Endl;

Matlab:

% to calculate gain% of RGB three channel

Rgain = Ymax/rav
Ggain = Ymax/gav
Bgain = Ymax/bav

Ymax = 235

Rav = 133.4989

Gav = 123.8576
Bav = 149.9403

Odd, you need to use the gain factor, but the output is an integer 2

Command calculation at the command line can clearly output floating-point results

/rdivide matlab Help document Explanation:

Integer Division

Divide a int16 scalar value by each element of the int16 vector.

A = Int16 (a);
b = Int16 ([3 4 6]);
x = a./b

x =

      3      3      2

Matlab®rounds the results when dividing integer data types. For integers, rounding the result is a solution:

Divides the% two integers, converts the denominator to a double, and the output is a double type.

SUMR = SUM (sum (R))
Rav = Double (SUMR)/CNDDT

Output results:
Rav = 133.4989
