# FAQ: How To Do Square Root In Fortran?

## How do you write square root in Fortran?

SQRT (X) computes the square root of X. The type shall be REAL or COMPLEX. Return value: The return value is of type REAL or COMPLEX.

## What is the command for square root?

In the Google search box, type the square root command – the sqrt symbol – and the number you want to know the square root of. For example, to find the square root of 75, type ” sqrt 75″ or “square root 75” and select “Enter.” As soon as you finish typing, Google displays the square root result.

## 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.

ALOG (or ALOG ‘) or ALOG10 ALOG calculates the natural logarithm of a positive real number; ALOG10 calculates the base 10 logarithm of a positive real number.

## What is a subroutine in Fortran?

A Fortran subroutine is a block of code that performs some operation on the input variables, and as a result of calling the subroutine, the input variables are modified. In Fortran, functions and subroutines are different: the former returns a value while the latter does not. Functions are simpler than subroutines.

## Where is the square root button on a laptop?

The shortcut for typing an under root symbol in Windows is by pressing Alt key + 251 on keypad of the keyboard. In few laptops, where keypad is not present, the symbol can be directly copied from character map. Moreover, if you want to use the symbol in MS Word, it can be inserted using insert equation option.

## Do loops in Fortran?

Fortran – Do Loop Construct

• the loop variable var should be an integer.
• start is initial value.
• stop is the final value.
• step is the increment, if this is omitted, then the variable var is increased by unity.

## How do you divide in Fortran?

In FORTRAN, addition and subtraction are denoted by the usual plus (+) and minus (-) signs. Multiplication is denoted by an asterisk (*). This symbol must be used to denote every multiplication; thus to multiply N by 2, we must use 2 * N or N * 2 not 2N. Operations.

Operator Operation
/ division
** exponentiation

## What is a Fortran module?

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 Tan inverse in Fortran?

9.23 ATAN — Arctangent function Description: ATAN(X) computes the arctangent of X. The type shall be REAL or COMPLEX; if Y is present, X shall be REAL. The type and kind type parameter shall be the same as X.

## What is intrinsic function in Fortran?

Fortran provides many commonly used functions, called intrinsic functions. the name and meaning of the function such as ABS() and SQRT() the number of arguments. the range of the argument. the type of the return value or the function value.
