WebFortran is a language with a long history. Fortran is one of the oldest Programming Languages still in active use. That old history means that the language has evolved in expression and scope over more than 60 years. The way you programmed Fortran back in the 60s, 70s, and 80s is completely inadequate for modern computers. WebAn if statement construct can have one or more optional else-if constructs. When the if condition fails, the immediately followed else-if is executed. When the else-if also fails, its successor else-if statement (if any) is executed, and so on. The optional else is placed at the end and it is executed when none of the above conditions hold true. friday television seriesWebVectorization Recommendations for C++ Vectorization Recommendations for Fortran Ineffective Peeled/Remainder Loop(s) Present Serialized User Function Call(s) Present Scalar Math Function Call(s) Present Inefficient Gather/Scatter Instructions Present Vector Register Spinning Possible Assumed Dependency Present Proven (Real) Dependency Is ... friday television ratings
