How do you do modulus in Fortran?
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.
What is a module in Fortran?
Advertisements. A module is like a package where you can keep your functions and subroutines, in case you are writing a very big program, or your functions or subroutines can be used in more than one program. Modules provide you a way of splitting your programs between multiple files.
What is E in Fortran?
d indicates that the fractional part of the number (the part to the right of the decimal point) has d digits. e indicates the number of digits in the exponent field. The default is 2. The specified input/output list item must be of type real.
How do I return in Fortran?
The RETURN statement transfers control from a subprogram to the calling program unit. Is a scalar expression that is converted to an integer value if necessary. The expr is only allowed in subroutines; it indicates an alternate return. (An alternate return is an obsolescent feature in Fortran 95 and Fortran 90.)
What do you mean by Modulus?
Definition of modulus 1a : the factor by which a logarithm of a number to one base is multiplied to obtain the logarithm of the number to a new base. b : absolute value sense 2.
How do you write not equal to in FORTRAN?
Fortran – Relational Operators
| Operator | Equivalent | Example |
|---|---|---|
| == | .eq. | (A == B) is not true. |
| /= | .ne. | (A != B) is true. |
| > | .gt. | (A > B) is not true. |
| < | .lt. | (A < B) is true. |
What is implicit none in Fortran?
The implicit none statement is used to inhibit a very old feature of Fortran that by default treats all variables that start with the letters i, j, k, l, m and n as integers and all other variables as real arguments. Implicit None should always be used.
What is pure function in Fortran?
A statement function is pure if and only if all functions that it references are pure. The specification_part of a pure function must specify that all dummy arguments have an INTENT(IN), except procedure arguments, arguments with the POINTER attribute, and arguments with the VALUE attribute .
How do you write power 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.
How do you write 10 to the power in Fortran?
A double-precision exponent consists of the letter D , followed by an optional plus or minus sign, followed by an integer. A double-precision exponent denotes a power of 10. The value of a double-precision constant is the product of that power of 10 and the constant that precedes the D .
Can a Fortran function return an array?
Functions in Fortran 90 can return an array !
How do you exit a subroutine in Fortran?
The return statement can be used to exit function and subroutine. Unlike many other programming languages it is not used to set the return value. This function performs an iterative computation.
