What is Nint in Fortran?

What is Nint in Fortran?

Description: NINT(A) rounds its argument to the nearest whole number. (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

What does C do in Fortran?

When a Fortran routine calls a C function: If the called C function returns a value, call it from Fortran as a function. If the called C function does not return a value, call it as a subroutine.

How do you set parameters in Fortran?

The PARAMETER statement assigns a symbolic name to a constant.

1. PARAMETER ( p = e [, p = e ] )
2. Example 1: Some real, character, and logical parameters:
3. Example 2: Let the compiler count the characters:
4. Example 3: The alternate syntax, if the -xl compilation flag is specified:
5. The above statement is treated as:

How do you write absolute value in Fortran?

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.

What does Nint mean?

NINT

Acronym	Definition
NINT	National Institute for Nanotechnology (Canada)
NINT	Northwest Institute of Nuclear Technology (Xi’an, Shaanxi, China)

What is Nint in calculus?

The nearest integer function, also called nint or the round function, is defined such that is the integer closest to . While the notation is sometimes used to denote the nearest integer function (Hastad et al.

Are arrays initialized to zero Fortran?

Many Fortran programs were developed on systems that provided automatic initialization of all, or some, variables and arrays to zero. You can ask g77 for this behavior by specifying the -finit-local-zero option when compiling Fortran code.

What are parameters in Fortran?

Fortran Parameters. A Fortran PARAMETER defines a named constant. If your compiler generates debug information for parameters, they are displayed in the same way as any other variable. However, some compilers do not generate information that TotalView can use to determine the value of a PARAMETER.

Which is the invalid statement in Fortran?

Which is the invalid statement in FORTRAN? P + Q + is the invalid statement in FORTRAN.

How do I find a remainder 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.

How do you define LN in Fortran?

9.177 LOG — Natural logarithm function Description: LOG(X) computes the natural logarithm of X , i.e. the logarithm to the base e. The type shall be REAL or COMPLEX .

How does the Nint function in Fortran work?

NINT(A) rounds its argument to the nearest whole number. Fortran 77 and later, with KIND argument Fortran 90 and later. Elemental function. RESULT = NINT(A KIND]) Returns A with the fractional portion of its magnitude eliminated by rounding to the nearest whole number and with its sign preserved, converted to an INTEGER of the default kind.

Which is the compiler for the Fortran compiler?

NINT (The GNU Fortran Compiler) Description: NINT (A) rounds its argument to the nearest whole number. Standard: Fortran 77 and later, with KIND argument Fortran 90 and later. Class: Elemental function. Syntax: RESULT = NINT (A [, KIND])

When to call an intrinsic function in Fortran?

The function may also be called by one of its specificnames to handle a specific argument data type. With functions that work on more than one data item (e.g. sign(a1,a2)), all the data arguments must be the same type. In the following tables, the FORTRAN 77 intrinsic functions are listed by:

Which is the nearest whole number ceiling in Fortran?

ANINT (A [, KIND]) Nearest whole number CEILING (A [, KIND]) Least integer greater than or equal to number CMPLX (X [, Y, KIND]) Conversion to complex type CONJG (Z) Conjugate of a complex number DBLE (A) Conversion to double precision real type DIM (X, Y)
