Rounding off to the next whole number
Hello,
I searched a lot on this Forum.
Please help me with the below problem.
I want to divide two numbers and the result should be the next nearest whole number.
E.G. Dividing 10.8/5 ideally gives 2.16. But the result should be 3 i.e. rounded off to the next whole number.
Any help will be deeply appreciated.

I am currently using tcsh
I am trying to round a decimal number to the ten-thousandths place
For instance:
1.23456 is rounded up towards 1.2346

It seems that perl sprintf uses the round-to-even method:
foreach my $i ( 0.5, 1.5, 2.5, 3.5 ) {
printf "$i -> %.0f\n", $i;
}
__END__
0.5 -> 0
1.5 -> 2
2.5 -> 2
3.5 -> 4
4.5 -> 4
Where we probably wants to use round-half-up, i.e. output should be as below:
0.5 -> 1
1.5 -> 2... (8 Replies)

raised. On Integrity servers, if the rounded value is outside the range of the numeric result is the minimum value.
When raises no other floating-point exception and the result differs from the argument, the function raises the inexact floating-point
exception.
