How to convert Float to String in C++ ?

Answer

To convert a float to a string in C++, you can use the std::to_string() function.

✐ Examples

1 Convert Float 3.14 to String

In this example,

We declare a float variable float1 with a value of 3.14.
We use the std::to_string() function to convert the float to a string and store the result in a string variable str1.
Finally, we print the string value str1.

C++ Program

#include <iostream>
#include <string>

int main() {
	float float1 = 3.14;
	std::string str1 = std::to_string(float1);
	std::cout << "String value is: " << str1 << std::endl;
	return 0;
}

Output

String value is: 3.140000

2 Convert Float 10.5 to String

In this example,

We declare a float variable float2 with a value of 10.5.
We use the std::to_string() function to convert the float to a string and store the result in a string variable str2.
Finally, we print the string value str2.

C++ Program

#include <iostream>
#include <string>

int main() {
	float float2 = 10.5;
	std::string str2 = std::to_string(float2);
	std::cout << "String value is: " << str2 << std::endl;
	return 0;
}

Output

String value is: 10.500000
