How to convert Float to String in C ?

Answer

To convert a float to a string in C, you can use the sprintf() 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 sprintf() function to convert the float to a string and store the result in a character array str1.
Finally, we print the string value str1.

C Program

#include <stdio.h>

int main() {
	float float1 = 3.14;
	char str1[20];
	sprintf(str1, "%f", float1);
	printf("String value is: %s\n", str1);
	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 sprintf() function to convert the float to a string and store the result in a character array str2.
Finally, we print the string value str2.

C Program

#include <stdio.h>

int main() {
	float float2 = 10.5;
	char str2[20];
	sprintf(str2, "%f", float2);
	printf("String value is: %s\n", str2);
	return 0;
}

Output

String value is: 10.500000
