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.
How do I round a number in Fortran?
If you want to round to the nearest integer, use NINT . So, in your case B and D are always 123 (if they are declared as integer ).
What is the difference between Fortran 90 and 77?
The first, and most obvious, change from FORTRAN 77 to Fortran 90 is the conversion from fixed source code to free source. (also known as a “bang”), is used to indicate a comment statement in Fortran 90. Obsolete features include the arithmetic IF statement, ASSIGN and GO TO statements.
What does Nint mean?
|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.
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.
How do you round off decimals in Fortran?
If you want to round off a floating point number to two decimal places, you can try the following:
- Multiply by 100.0.
- Use ANINT to round to the nearest integer value.
- Divide by 100.0.
Is Fortran 77 still used?
Fortran has through many revisions, the most well known are the 66, 77, 90, 95, 03, and 08 standards. It is often said that the reason Fortran is still used is that it is fast. Interestingly, C++ beats Fortran on all but two of the benchmarks, although they are fairly close on most.
What is mean mint?
1 : a place where coins, medals, or tokens are made. 2 : a place where something is manufactured. 3 : a vast sum or amount worth a mint.
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.
Are there any numerical functions in Fortran 90?
Numerical functions: The following are available from Fortran 77: ABS, AIMAG, AINT, ANINT, CMPLX, CONJG, DBLE, DIM, DPROD, INT, MAX, MIN, MOD, NINT, REAL and SIGN. In addition, CEILING, FLOOR and MODULO have been added to Fortran 90.
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])
Are there any intrinsic functions in FORTRAN 77?
The following functions from Fortran 77 can use a kind-parameter like in AINT(A, kind), namely AINT, ANINT, CMPLX, INT, NINT and REAL.
