void setTextPosition(float a, float b); int main(){    setTextPosition(static_cast<int>(posX), static_cast<int>(posY)); //Note posX and posY are floats and i really need to pass int values the setTextPosition is a sfml2.0 function and i don't want to mess with sfml code}

You can use #pragma warning to disable specific warnings. If you want to disable it for just one line you can use #pragma warning(suppress : 4244).

Thank you kind sir.

int a = 100;

float b = (float)a;

You can also use a proper static_cast:

int a = 100;
float b = static_cast<float>(a); // int to float

Or:

float b = 100.0f;
int a = static_cast<int>(b); // float to int

You can also use a proper static_cast:

int a = 100;float b = static_cast<float>(a); // int to float

Or:

float b = 100.0f;int a = static_cast<int>(b); // float to int

float posX;float posY;int main(){    setTextPosition(static_cast <int> (posX) ,static_cast <int> (posY) ) ;    return 0;}

I really don't understand why you're casting floats to ints for a function that takes floats. If you want to change them to whole numbers you should just cast them seperately to remove the ambiguity or use some kind of round function instead of shearing the last bits off by casting. Rounding would actually be better if you're trying to move them closer to a logical position.

Often warnings are there for a reason and I'm not sure why people are so apt to disable them when the extra code to disable them could just as easily -fix- the warning.

Reason behind this is:
In the function, if posX and posY are not round numbers the text may appear blurry. Therefore i cast them to int before passing into function to remove occasion of blurry text.

You probably want to use std::floor instead of casting to int.
