This is my first day in the 100 Days of Code challenge. Today, I had started with the “Fortran for Scientific Computing” course in Future Learn. It had been a great start.
I had learnt about the precision available in fortran for various number data types. For example, the follow program deals with the single and double precision for real numbers.


It gives out the following result when compiled(gfortran 0 sqrt_2 sqrt_2.f90
) and run(./sqrt_2
).

Next, I’ll be looking into the strings and related operations in Fortran.
