float or scalar for runTime.tinename() ??

Canesin · February 2, 2011, 13:26

I had look around but I'm not finding a method to call to provide the time the simulation is on.. I wan't to make a change when time = changetime..

I have tried to do casting like:

float(runTime.timeName()) but it do not work.... I'm starting to believe I will have to implement the casting..

Hi Fábio,

Type casting only works when the variables are similar, for example between pointers and between double/int/float and so on. To convert a string to float, you can use atof.

But I think that runTime.value() will get you the value already in scalar (float or double) format, without the need to convert the value.

Best regards,
Bruno

LOL ...

Thanks Bruno, I had looked at the doxygen but the method "value()" was not there, I believe it's because it is from inheritance..

You should always check the fine print
