Simple Answer use macro to generate this output

Why not just do a string concatenation operation?

Here is my solution using a C/C++ style string concatenation approach:

double oneNumberDotTheOther(int a, int b)
{
ostringstream oVV;
oVV << a << "." << b;
string zVV = oVV.str();
double fVal = atof(zVV.c_str());
return fVal;
}

public double concatDecimal(int a, int b){
return Double.parseDouble(a + "." + b);
}

Do people just think the case b has more than 2 digits?

#
#
#write a function that takes two numbers a and b and returns a.b eg: a=10 and b=12 output will be 10.12
#
#
#

import math
#def to_decimal(a, b):
#	return float(str(a) + "." + str(b))

def to_decimal(a, b):
	if b is not 0:
		return a + (float(b) / (10.0 ** (math.floor(math.log10(b) + 1.0))))
	else:
		return a + 0.0

print to_decimal(567, 789)
print to_decimal(1234, 567)
print to_decimal(1234, 000)
print to_decimal(1234, 100)

int a =10;
		int b = 12;
		String c = a + "." + b;
		System.out.println(c);

Alternatively you can also return the variable c

package number.manipulation;

/* write a function that takes two numbers a and b and returns a.b eg: a=7 and b=24 output will be 7.24 */

public class NumberManipulation {

	public double create(int a, int b) {
		int n = b;
		int count = 0;
		while (n > 0) {
			count++;
			n /= 10;
		}

		return (double) a + ((double) b / Math.pow(10, count));
	}

	public static void main(String[] args) {
		NumberManipulation nm = new NumberManipulation();
		double result = nm.create(7, 24);
		System.out.println(result);
	}

}

int a,b;
cin>>a>>b;
string result=to_string(a) + '.' + to_string(b);
cout<<result<endl;
