What does MOD function do 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 are .MOD files in Fortran?

mod files are auto-generated by the compiler from the source files and they are compiler dependent (that is, a Fortran compiler can only use module files produced by that specific compiler). If a. f90 contains the statement module a then compiling a. f90 will produce both a.o and the module definition file a.

How do I round in Fortran?

Instead you can use INT to remove all the decimal places and FLOAT to return the variable to a real. It is standard practice to round numbers up by adding 0.5 before taking the integer.

What is return in FORTRAN?

Return (in Subroutines) A return statement in a subroutine instructs Fortran to terminate the subroutine and return to the main program at the point where it departed. Thus it works like a stop statement in the main program, halting the program prematurely before the final end statement.

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.

How do I declare double precision in Fortran?

For a declaration such as DOUBLE PRECISION X , the variable X is a REAL*8 element in memory, interpreted as one double-width real number. If you do not specify the size, a default size is used.
