Why when using QT the type of the variables of my scripts change "float" to "int" ?

RoiG

Hello,

I have a dynamic library A.dll that has a script system (chaiscript).

When I link this A.dll library with a B.exe program that I use to test the library and execute a script, it works as expected:

def update() {
var dt = 0.1f;
var speed = 50.0f;
var movement = speed * dt;
print("dt: " + to_string(dt) + " speed: " + to_string(speed) + " movement: " + to_string(movement));
.....

prints:

 dt: 0.1 speed: 50 movement: 5

NOW THE PROBLEM:

When I use QT and link to the same A.dll, and the QT application executes the script using A.dll library it prints this:

prints:

 dt: 0 speed: 50 movement: 0

As you can see the floating variables are truncated to INT.

Anyone knows if QT is doing something weird with the built-in types?
Thank you!

to_string

Make sure u are using QString::number to convert for output
float pi = 3.14;
QString b = QString::number(pi);

Else It should not fux with the types.

Edit: sorry , Py . Not sure that the actual issues.

Hello, thank you for your answer but the to_string method is a method from chaiscript script system not the QT one.

I'm not using the QT types for the script, just built-in types like int float etc..

@RoiG
well seems a bit odd.
Does this apply to all py variables u define?

RoiG

py == python? It's chaiscript, and yes it happens to all variables that I define :(

I asked the same on the chaiscript forum, the main programmer of chaiscript, said the same "That's very odd" :P

I suppose that I will have to make an small test case..

Thank you! :)

mrjj

sorry. my bad.
Its was the "def" that made my brain go py.

yeah I think u need a small test case as Qt should not mess with the build in types as far as I know
since it has its own ones. quint32 etc.

Good luck!
