Hello everyone,
I have a problem. I want to divide one number(Real data type, i need it as real, because numbers behind comma have importance too) with number 3600. How can i do that? When I try to use DIV, I get some kind of number(*e-003), even when i try to divide 10.0/3600.0 i get 2,77e-003, although i should get 0.002777**, is there any possible solution how to scale the output or round it? Thanks for every reply

VAR
inputtime:TIME; ( here you start making the difference)
inputdivider:real:=3600; ( make sure this is a real variable when you type in th eprogram 3600 it is treated as an INT)
workingtime:real; ( for holding the converted time just to let you see if it works)
outputhours:real;
END_VAR

program:
workingtime:=TIME_TO_REAL(inputtime);
outputhours:=DIV(workingtime,inputdivider);

RETURN
This can best be done in a function block in FBD for example.
make the inputdivider GLOBAL (put all constants and upthere i use even zero and 1 as reals in GLOBAL

Correct result actually:
2,77777e-003 = 2,77777 *10^-3= 2,77777 * (1/1000) = 0.002777

So it's only a display thing in the CodeSys debugger.

old problem , but display with %1.6f or anything you like.
yes rounding is also possible, but not accurate.
