How do you write modulus in Fortran?

How do you write 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.

Does modulo truncate?

When the result of a modulo operation has the sign of the dividend (truncating definition), it can lead to surprising mistakes. But in a language where modulo has the sign of the dividend, that is incorrect, because when n (the dividend) is negative and odd, n mod 2 returns −1, and the function returns false.

How do you write not equal to in FORTRAN?

All relational operators have equal precedence. Character and arithmetic operators have higher precedence than relational operators….Relational Operator.

Operator	Meaning
.LT. .LE. .EQ. .NE. .GT. .GE.	Less than Less than or equal Equal Not equal Greater than Greater than or equal

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.

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 exponential in Fortran?

9.102 EXP — Exponential function 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 .

How does modulo operator work?

The modulus operator, sometimes also called the remainder operator or integer remainder operator works on integers (and integer expressions) and yields the remainder when the first operand is divided by the second. The syntax is the same as for other operators.

What are the six relational operators in Fortran?

There are six relational operators:

• LT. less than.
• LE. less than or equal to.
• EQ. equal to.
• GE. greater than or equal to.
• GT. greater than.
• NE. not equal to.

What are the 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.
