# arithmetic operators in fortran

Table: Arithmetic Operators. Arithmetic Operations FORTRAN variables and constants can be processed using operations and functions appropriate to their types. The five arithmetic operators in FORTRAN are: 1. BYTE @. REAL*16 (SPARC only) @. Multiplication * 4. The arithmetic operations on complex numbers are all represented by the same operators as for the REAL or INTEGER numbers. For Fortran or any similar language, you must include the name of a variable (shorthand for a memory address) to the left of the "=" to receive the results of the operations to the right of the "=". Fortran has five LOGICAL operators that can only be used with expressions whose results are logical values (i.e., .TRUE. 4.8 FORTRAN 90 - PRINT statement. Arithmetic Operators The mathematical symbols that can be used in Fortran and the corresponding mathematical symbol is given in the following table. DOUBLE COMPLEX @. REAL. 4.7 Mixed Mode aritmetic. LOGICAL. Since I am not experienced in the programming language Fortran in my example I came across a problem where the compiler reports the following errors to me: Arithmetic Expressions. 4.3 Concept of a computer variable. or .FALSE.All LOGICAL operators have priorities lower than arithmetic and relational operators. Fortran 77 : 3. 4.2 Arithmetic operations. Exponentiation ** An arithmetic expression evaluates to a single arithmetic value, and its operands have the following types. Arithmetic Operators Table below shows the arithmetic operators. Simple Arithmetic Operators Operators in Fortran expressions are about what you would expect from other experiences, except perhaps exponentiation: 4.6 Integer division. Arithmetic. The same symbols are used for integer (INTEGER), real (REAL, DOUBLE PRECISION REAL) and complex (COMPLEX, DOUBLE PRECISION COMPLEX) arithmetic. The basic arithmetic operations of addition, subtraction, multiplication, division, & exponentiation (raising to the power) are all possible in FORTRAN 77. COMPLEX. The operations and their operators are listed in the Table 11.1. 4.5 Implicit declarations in FORTRAN. Subtraction - 3. The following list shows the Intel Fortran arithmetic operators, from fastest to slowest: Addition (+), Subtraction (-), and Floating-point multiplication (*) Integer multiplication (*) Division (/) Exponentiation (**) Avoid Using EQUIVALENCE Statements Two operators cannot be written consecutively. precedence of arithmetic operators in Fortran 77 are (from highest to lowest): ** {exponentiation} *,/ {multiplication, division} +,- {addition, subtraction} All these operators are calculated left-to-right, except the exponentiation operator **, which has right-to-left precedence. Table 3-1 Arithmetic Operators 4.9 Design and setup of a complete program Addition + 2. Fortran provides for all the basic Arithmetic operations. INTEGER. LOGICAL Operators and Expressions . The arithmetic operators are +,- plus and minus *,/ multiply and divide ** exponentiation (raise to the power) () brackets The order of precedence in FORTRAN is identical to that of mathematics. 4.4 Declaration statements. Replacing slow arithmetic operators with faster ones should be reserved for critical code areas. The operators for an arithmetic expression are any of the following: . Division / 5. I intend to define a user type that would look like a complex number but would also allow the arithmetic operation of adding two complex numbers. Operations must be defined in a particular sequence as is done in a simple mathematics using BODMAS rule. 2. But here the rules are slightly different from standard BODMAS. DOUBLE PRECISION. COMPLEX*32 (SPARC only) @. You can use the addition and subtraction operators with one or two operands; in the latter case, specify the operator before the operand; for example, –TOTAL. @ indicates a nonstandard feature. Addition as well as subtraction in FORTRAN 77 ownership the same familiar symbols + moreover to - . Operands of an arithmetic operation may be a numeric constant, numeric variable or an arithmetic expression in parentheses.
