Answer:
The function is written in C++
bool products(double num1, double num2, double num3) {
 if(floor(num1 * num2) == floor(num3)){
     return true;
 }
 else
 {
     return false;
 }
}
Explanation:
I answered this question using C++ programming language.
This line defines the function with three parameters; num1 to num3
bool products(double num1, double num2, double num3) {
This checks if the floor of num1 * num2 equals floor of num3
 if(floor(num1 * num2) == floor(num3)){
If yes, this returns true
     return true;
 }
 else {
If otherwise, this returns true
     return false;
 }
The method ends here
