Version comparing

I am doing the following to compare versions

Var t1 

Var t2



Function compare

strcpy $t1 '1.2.0.0' ;just for the example

strcpy $t2 '1.3.0.0' ;just for the example

${StrReplace} '$t1' '.' '' '$t1'

${StrReplace} '$t2' '.' '' '$t2'

${If} $t1 < $t2

     messagebox MB_OK "$t1 is smaller"

${EndIf}

is this the correct way to do it ?

Did you see the included version compare function?

Thanks
