- The assignment
operator is
=
Example:
double precision r r = 3.14;
- Unlike
C/C++ ,
the assignment operation
of Fortran
does NOT cascade
double precision r1, r2 r2 = r1 = 3.14 ! Illegal
- Fortran Arithmentic Operators listed in order of precidence:
** exponentation * , / multiply, divide + , - add, subtract Example:
integer i, j, k real x, y, z i = 2; j = 3; k = i**j ! Cube x = 2; y = 0.5; z = x**y ! Square root....

Well, based on we havce learned in C++,
you should know what to do with these operators...
But don't worry, you will see how these operators are used later...
