frexp() function in c language: -

frexp() function in c programming will splites a floating-point value into a fraction and an exponent . Here fraction value is return by frexp function and exponent is stored by exp variable in c.

Synatx : - 

double frexp(double value, int *exp);

remember that fraction must be greater than or equal to 0.5 and less than 1. or it can be zero or must be equal to zero.

    int e;
    double f;

    /* Assign the value we will find the exp of */
    value = 1.5;

    /* Calculate the fraction and exponential of the value */
    f = frexp(value, &e);

    /* Display the result of the calculation */
    printf("The Fraction and Exponential of %f are %f and %d\n", value, f, e);

    return 0;
}

Output : -

 Fraction and Exponential of 1.500000 are 0.750000 and 1
