3.1.3.5 Roundup (ROUNDUP)
Input values, type REAL (fractions with decimal point) can be rounded up to the next higher
integer number using the ROUNDUP" function.
Syntax
ROUNDUP(<value>)
Meaning
ROUNDUP: Command to roundup an input value
<value>: Input value, type REAL
Note
Input value, type INTEGER (an integer number) is returned unchanged.
Examples
Example 1: Various input values and their rounding up results
Example Rounding up result
ROUNDUP(3.1) 4.0
ROUNDUP(3.6) 4.0
ROUNDUP(-3.1) -3.0
ROUNDUP(-3.6) -3.0
ROUNDUP(3.0) 3.0
ROUNDUP(3) 3.0
