NAME

NINT, IDNINT, ININT, JNINT, KNINT - Convert to nearest integer

SYNOPSIS

NINT ([A=]a [,[KIND=]kind])
IDNINT ([A=]a [,[KIND=]kind])
ININT ([A=]a)
JNINT ([A=]a)
KNINT ([A=]a)

STANDARDS

Fortran

Fortran extensions: IDNINT, ININT, JNINT, KNINT

DESCRIPTION

NINT is the generic function name; the others are specifics. These are elemental intrinsic functions. They accept the following arguments:

a: Must be type real. See the RETURN VALUES section for information on input data types and return values.
kind: A scalar integer initialization expression. Must be a kind type allowed for a.

These functions find the nearest integer for real numbers, using these equations:

If a >= 0, y= INT(a+.5).
If a < 0, y= INT(a-.5).

NOTES

The NINT and IDNINT intrinsic function names can be passed as arguments; the others cannot.

Note: The nint() function has a Linux-equivalent name. Use the man -aname option to show all manual pages matching name within the MANPATH search path. Manual pages are displayed in the order found.

RETURN VALUES

NINT returns the nearest INTEGER for its REAL argument.

IDNINT returns the nearest INTEGER for its double-precision argument.

ININT returns an INTEGER(KIND=2) for its REAL argument.

JNINT returns an INTEGER(KIND=4) for its REAL argument.

KNINT returns an INTEGER(KIND=8) for its REAL argument.
