ANINT Function
•
If ABS (x) > 1.0, AINT returns the integer whose magnitude is the largest integer
that does not exceed the magnitude of x and whose sign is the same as that of x.
Examples of the AINT Function
x = DINT (y)
a = AINT (.01 * c)
ANINT Function
The ANINT function returns the whole number that is closest in value to its argument.
The table below shows the argument and function type for the ANINT function and its
associated specific function.
Considerations
•
The result type of the ANINT function is the same as the type of its argument.
•
If x is zero, ANINT returns zero.
•
If x is greater than zero, ANINT returns:
AINT (x + 0.5)
•
If x is less than zero, ANINT returns:
AINT (x - 0.5)
Example of the ANINT Function
esttax = ANINT (price) * .07 * items
