By default a real number is treated as a
Answer: Option
Explanation:
In computing, 'real number' often refers to non-complex floating-point numbers. It include both rational numbers, such as 42 and 3/4, and irrational numbers such as pi = 3.14159265...
When the accuracy of the floating point number is insufficient, we can use the double to define the number. The double is same as float but with longer precision and takes double space (8 bytes) than float.
To extend the precision further we can use long double which occupies 10 bytes of memory space.

a==a or b==b means it comes I love you..
OR
a==b or b==a means it comes I hate you..
It checks the var equalization.

The numbers which are in set are 1, 2, 3. 1/2, 1/3, -. -1, -2. Etc are real nos.
By default its datatype is considered as doubled.

Real number means floating point numbers. For eg. 2.5, 20.5 etc.

But real constants are called as floating point constants then how?

Hello Cheluvarajesh.
Double variable is always bigger than the Float variable whether the values are same.

Double variable have more precision.
for eg.,
6/36=0.166666666
So we can get more over approximate value

We know how machine language gets work.Compiler can convert our all source codes to 0's & 1's. Float can occupy memory space:4 bytes. Double can occupy memory space:8 bytes. so, if we specify float a=1 or double b=1 it considered as 4bytes & 8bytes respec with same value as 1.0000etc. but if we specify float a=1.1,double b=1.1 the bit values for float and double may be unequal.so, it shows the result based on the condition.
