### Exercise :: Floating Point Issues - General Questions

1.

What are the different types of real data type in C ?

 A. float, double B. short int, double, long int C. float, double, long double D. double, long int, float

Explanation:

The floating point data types are called real data types. Hence float, double, and long double are real data types.

2.

What will you do to treat the constant 3.14 as a long double?

 A. use 3.14LD B. use 3.14L C. use 3.14DL D. use 3.14LF

Explanation:

Given 3.14 is a double constant.

To specify 3.14 as long double, we have to add L to the 3.14. (i.e 3.14L)

3.

If the binary eauivalent of 5.375 in normalised form is 0100 0000 1010 1100 0000 0000 0000 0000, what will be the output of the program (on intel machine)?

``````#include<stdio.h>
#include<math.h>
int main()
{
float a=5.375;
char *p;
int i;
p = (char*)&a;
for(i=0; i<=3; i++)
printf("%02x\n", (unsigned char)p[i]);
return 0;
}
``````

 A. 40 AC 00 00 B. 04 CA 00 00 C. 00 00 AC 40 D. 00 00 CA 04

 A. 3.4E-4932 to 1.1E+4932 B. 3.4E-4932 to 3.4E+4932 C. 1.1E-4932 to 1.1E+4932 D. 1.7E-4932 to 1.7E+4932

Explanation:

The range of long double is 3.4E-4932 to 1.1E+4932

5.

Which statement will you add in the following program to work it correctly?

``````#include<stdio.h>
int main()
{
printf("%f\n", log(36.0));
return 0;
}
``````

 A. #include B. #include C. #include D. #include

Explanation:

math.h is a header file in the standard library of C programming language designed for basic mathematical operations.

Declaration syntax: double log(double);
