It is much neater and faster to use sprintf, rather than num2str and concatenating strings together:
>> x = 1;
>> y = 2;
>> sprintf('The winning number is %d and the price is %d', x, y)
ans =
The winning number is 1 and the price is 2
Note that there are many options for converting numeric values (precision,, leading and trailing zeros, etc), so please read the sprintf documentation carefully and pick the format that suits your application best!

you can use the function num2str() to convert the double to a string.
x = 1
y = 2
outputstring = ['the winning number is ' num2str(x) ' and the price is ' num2str(y)]
