How do I find the maximum of an array in Fortran?
How do I find the maximum of an array in Fortran?
8.191 MAXVAL — Maximum value of an array Determines the maximum value of the elements in an array value, or, if the DIM argument is supplied, determines the maximum value along each row of the array in the DIM direction. If MASK is present, only the elements for which MASK is . TRUE.
What is intrinsic function in Fortran?
Intrinsic functions that are Sun extensions of the ANSI FORTRAN 77 standard are marked with @ . Intrinsic functions have generic and specific names when they accept arguments of more than one data type. In general, the generic name returns a value with the same data type as its argument.
How does Fortran calculate remainder?
MOD(A,P) computes the remainder of the division of A by P. It is calculated as A – (INT(A/P) * P) . Return value: The kind of the return value is the result of cross-promoting the kinds of the arguments.
Does Fortran use radians or degrees?
Note that all trigonometric functions use radian rather than degree for measuring angles.
How do you write absolute value in Fortran?
8.3 ABS — Absolute value ABS(A) computes the absolute value of A . The type of the argument shall be an INTEGER , REAL , or COMPLEX . Return value: The return value is of the same type and kind as the argument except the return value is REAL for a COMPLEX argument.
How do you write not equal to in Fortran?
Relational operators
| Operator | Equivalent Operator | Meaning |
|---|---|---|
| != | .NE. | X is not equal to Y |
| == | .EQ. | X is Equal to Y |
| > | .GT. | X is greater than Y |
| < | .LT. | X is less tah Y |
What are the types of intrinsic functions are there in Fortran?
Fortran – Intrinsic Functions
- Numeric Functions.
- Mathematical Functions.
- Numeric Inquiry Functions.
- Floating-Point Manipulation Functions.
- Bit Manipulation Functions.
- Character Functions.
- Kind Functions.
- Logical Functions.
Does Fortran have a main function?
7.4 FORTRAN Functions A FORTRAN function is a procedure whose result is a single number, logical value, character string or array. There are two types of functions, intrinsic and user-defined. Intrinsic functions are those functions built into a FORTRAN language, such as SIN(x) or LOG(x).
How do you make a modulo in Fortran?
MODULO(A,P) has the value R such that A=Q*P+R , where Q is an integer and R is between 0 (inclusive) and P (exclusive). If A and P are of type REAL : MODULO(A,P) has the value of A – FLOOR (A / P) * P . The returned value has the same sign as P and a magnitude less than the magnitude of P.
How do you write LOG10 in Fortran?
LOG10(X) computes the base 10 logarithm of X . The type shall be REAL . Return value: The return value is of type REAL or COMPLEX .
How do you do powers in Fortran?
In addition to addition +, subtraction -, multiplication * and division /, Fortran has an exponential operator **. Thus, raising X to the Y-th power is written as X**Y. For example, the square of 5 is 5**2, and the square root of 5 is 5**0.5. The exponential operator has the highest priority.
What does .lt mean in Fortran?
Logical expressions can only have the value .TRUE. or .FALSE.. A logical expression can be formed by comparing arithmetic expressions using the following relational operators: .LT. meaning < .LE. <= .
What are the five logical operators in Fortran?
Fortran – Logical Operators
| Operator | Description |
|---|---|
| .not. | Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false. |
| .eqv. | Called Logical EQUIVALENT Operator. Used to check equivalence of two logical values. |
Can a Fortran function return an array?
Functions in Fortran 90 can return an array !
Does Fortran do Enddo?
The END DO statement is the delimiting statement of a Block DO statement. If the statement label is not specified in a DO statement, the corresponding terminating statement must be an END DO statement. You can branch to an END DO statement only from within the range of the DO loop that it terminates.
Is Fortran case sensitive?
C and Fortran take opposite perspectives on case sensitivity: C is case sensitive–case matters. Fortran ignores case.
How do you write exponential in Fortran?
EXP(X) computes the base e exponential of X . The type shall be REAL or COMPLEX . Return value: The return value has same type and kind as X .
What is an intrinsic function in Fortran?
(For information about Fortran library routines, see theFortran Library Reference.) Intrinsic functions that are Sun extensions of the ANSI FORTRAN 77 standard are marked with @. Intrinsic functions have genericand specificnames when they accept arguments of more than one data type.
What does max mean in Fortran?
9.189 MAX — Maximum value of an argument list. Returns the argument with the largest (most positive) value. Fortran 77 and later. Elemental function. RESULT = MAX(A1, A2 A3 [.]]) The return value corresponds to the maximum value among the arguments, and has the same type and kind as the first argument.
What are the various miscellaneous functions in Fortran?
Other miscellaneous functions include bitwise functions, environmental inquiry functions, and memory allocation and deallocation functions. Bit Manipulation @ None of these functions are part of the FORTRAN 77 Standard. Table 6-6 Bitwise Functions Bitwise Operations No. of Args. Specific Name Argument Type Function Type Complement 1 NOT
Is bit clear an intrinsic or extrinsic function in Fortran?
LOGICAL Bit clear 2 IBCLR INTEGER INTEGER The above functions are available as intrinsic or extrinsic functions. See also the discussion of the library bit manipulation routines in theFortran Library Referencemanual. Environmental Inquiry Functions @ None of these functions are part of the FORTRAN 77 Standard.
