[.net] Conversion UINT' to 'FLOAT
Author
Anyone know of a any way to convert UINT to FLOAT. I knew of a function, but I seem to have forgot it.
Thanks.
I believe it is System.Convert.ToDecimal() For anything else take a look at the Convert Class. If that's not it, this is then (I hope [lol]). Well I mean go from UINT->DECIMAL->FLOAT, but there's probabally a simpler way someone more familiar with .Net knows of.
You should be able to do regular typecasting:
I mean if you are going from UINT to FLOAT, you are just adding on a .0000000 because an UINT is a whole number. That's what the typecasting does for you.
Thanks for pointing that out. I don't like the renaming convention that takes place in .Net [headshake]. Couldn't find any references to float.
// method 1unsigned int value = 25;float myNumber = (float)value;// method 2unsigned int value = 25;float myNumber = static_cast<float>(value);I mean if you are going from UINT to FLOAT, you are just adding on a .0000000 because an UINT is a whole number. That's what the typecasting does for you.

"cannot convert from 'float' to 'FLOAT *__w64 '"
I get this error when I use typecasting, forgot about that.

Where you are getting that error, you should be using &variable, rather than just variable. It's saying it cannot convert from a float to a float pointer. Can you post some code so we can see exactly what you are doing.

I am simply getting some info from directx about a image, taking its height then the direct3d surface and calculating the x and y values for a direct3d vector, that way I can set scale for my images. I had issues with scaling and thought of fixing it this way.
&m_Scale.x = static_cast<float>(imageInfo.Width / desc.Width);
&m_Scale.y = static_cast<float>(imageInfo.Height / desc.Height);
I know about the pointer and such, but when I did it I got the error. Thats the problem it has to be a pointer and make refrences else all my objects will be the same shape. Removing the pointer makes it work but only one sprite shows.
&m_Scale.x = static_cast<float>(imageInfo.Width / desc.Width);
&m_Scale.y = static_cast<float>(imageInfo.Height / desc.Height);

Any reason you are trying to assign to the address of those variables?
Could you not just go
m_Scale.x = (float)(imageInfo.Width / desc.Width);
m_Scale.y = (float)(imageInfo.Height / desc.Height);
That's how I would do it

Ahh that sounds like a DirectX problem as for why not both sprites are showing. As for the code:
Should be what you need if imageInfo, desc, and m_Scale are not pointers. What are the variable declarations of all those variables that you use? Can you list m_Scale, m_Scale.x, m_Scale.y, imageInfo, imageInfo.Width, desc, desc.Width, imageInfo.Height, and desc.Height.
