The range of the float data type in C is typically defined by the IEEE 754 standard for single-precision floating-point numbers. The approximate range is:
- Minimum positive value:
1.175494e-38 - Maximum positive value:
3.402823e+38
The exact range can vary slightly depending on the implementation and the compiler, but these values are generally accepted for most systems that adhere to the IEEE 754 standard.
You can also check the limits of the float type using the <float.h> header, which defines constants for the minimum and maximum values:
#include <stdio.h>
#include <float.h>
int main() {
printf("Minimum positive float: %e\n", FLT_MIN);
printf("Maximum float: %e\n", FLT_MAX);
return 0;
}This code will output the minimum and maximum values for the float data type on your system.
