Write a C program that finds and prints the machine epsilon for the float and double data types. Also print the values of __FLT_EPSILON__ and __DBL_EPSILON__ defined in float.h. Reminder – the phrase data type tells how the compiler “understands” the ones and zeros you are working with. This identifies whether you are working with integers, letters, real numbers, and so on.
Another definition:Machine epsilon is the "distance" between the number 1 and its immediate right neighbor.
We work in binary (decimal is in parentheses):
1 + 0,1 = 1,1 (1 + 1/2 = 1,5)
1 + 0,01 = 1,01 (1 + 1/4 = 1,25)
1 + 0,001 = 1,001 (1 + 1/8 = 1,125)
then, due to the limited accuracy of the computer at a certain number of decimal places, a situation arises where 1 + 0.0…001 = 1 (instead of the correct 1.0…001). Then the previous number 0.0…01 is called the machine epsilon . It is obvious that its value may be different on different computers. However, the machine…
Write a program that performs a rotational bit shift to the right for a positive integer. The user enters a number, the number of bits to shift (and, if you want, the direction of the shift, but right is enough).
Example:The number 9 (in binary form 1001) when rotated to the right by 1 bit becomes 1100.
Tip : A bit rotation (also known as a cyclic shift) is an operation in which the bits in a binary number are shifted a certain number of places to the right or left, with bits that “fall out” at one end being returned to the opposite end. So, start with a bit shift operation. Write a few examples on paper before programming.Tip : Use the unsigned int data type.You can get the number of bits of this data type as follows: int bit_count = sizeof (unsigned int ) * 8
