WebLOGICAL Operators and Expressions LOGICAL Operators and Expressions Fortran has five LOGICAL operators that can only be used with expressions whose results are logical values ( i.e., .TRUE. or .FALSE. ). All LOGICAL operators have priorities lower than arithmetic and relational operators. WebNov 8, 2024 · Seems like gfortran thinks unary operators have higher precedence than binary operators (at least for this case, it calculates the unary '-' operator, then division and multiplication from left to right) and I think this implementation (for this example) is more intuitive to me. But, how about -3**2? In this case, I am expecting a result of -9.

WebFortran 90 introduces new symbols, including the exclamation mark, the ampersand, and the semicolon, and the alternative form of relational operators. These are dis-cussed in the following paragraphs. The exclamation mark introduces a comment. A comment can start anywhere on a source line and thus can be placed alongside the relevant code. WebAn operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. Fortran provides the following types of operators − Arithmetic Operators Relational Operators Logical Operators Let us look at all these types of operators one by one.
