For calculation, FORTRAN is good. It is easy to learn. There are many kinds of FORTRAN. To choose good compiler is important to do work well. And, try to understand the math function, which is contained in the compiler, more deeply for doing more exact calculation. Knowing the limitations of the compiler is also important, too.

The language which has been developed before is difficult to learn. We learned summation at the school. But computer uses do , for, etc., similar expression. I think that the program language more closed to math book is ease to learn.
