Elemental Intrinsic Function (Generic): Calculates the nearest whole number.
Syntax
Results
The result type is real. If kind is present, the kind parameter is that specified by kind; otherwise, the kind parameter is that of a. If a is greater than zero, ANINT (a) has the value AINT (a + 0.5); if a is less than or equal to zero, ANINT (a) has the value AINT (a - 0.5).
Specific Name | Argument Type | Result Type |
---|---|---|
ANINT | REAL(4) | REAL(4) |
DNINT | REAL(8) | REAL(8) |
QNINT | REAL(16) | REAL(16) |
To truncate rather than round, use AINT.

Examples
ANINT (3.456) has the value 3.0.
ANINT (-2.798) has the value -3.0.
Consider the following:
REAL r1, r2
r1 = ANINT(2.6) ! returns the value 3.0
r2 = ANINT(-2.6) ! returns the value -3.0
! ANINT.F90 Calculates and adds tax to a purchase amount.
REAL amount, taxrate, tax, total
taxrate = 0.081
amount = 12.99
tax = ANINT (amount * taxrate * 100.0) / 100.0
total = amount + tax
WRITE (*, 100) amount, tax, total
100 FORMAT ( 1X, 'AMOUNT', F7.2 /
+ 1X, 'TAX ', F7.2 /
+ 1X, 'TOTAL ', F7.2)
