round() will round to the closest number. For example:

% expr round(1.2)
1
% expr round(1.6)
2

floor() will round to the lower and ceil() will round to the greater.

% expr floor(1.6)
1.0
% expr ceil(1.6)
2.0

int() will cut off string after the decimal point, round() will do the same, but adding 0.5 before doing so .

Ok it works, but now I have a double value for the result. How can I convert it to integer ?

Add a decimal point to the number you're dividing by. For example:

Code:

set c [expr (($a / 100.) * ($sum / 100.)) * 100]

Hi, I have a problem with the decimal numbers. How can make my script to show and calculate decimal numbers ? Should I use the package "Decimal arithmetic" or there is other way to do what I need ?

This is a sample of that what I'm trying to do:

Code:

set a 12; set b 20; set sum [expr ($a + $b)]set c [expr (($a / 100) * ($sum / 100)) * 100]set d [expr (($b / 100) * ($sum / 100)) * 100]
