Problem with modulus!!!

[sergelaurent]

For exemple;
set toto [expr 5 - 10]

toto's value would be -5!!!

I want to have the modulus of toto!!!

Can someone tell me hos I can do this?

Hi

[tt]abs()[/tt] ?

set toto [expr [red]abs([/red]5 - 10[red])[/red]]

The modulus function has to do with remainders. It is, therefore, related to division, not subtraction. Tcl has a modulus function, if that is what you want.

fmod(x, y)
Returns the floating-point remainder of the division of x by y. If y is 0, an error is returned.

So if you want, say, [red]10 modulo 5[/red], that would be

expr {fmod(10,5)}

Hi

So you too understood it that way. Only after aswers.coming for "modulus" I decided to give the solution with [tt]abs()[/tt], mostly because the question's subtraction example.

I would like to know what sergelaurent wants.
