.hpp and floats

[lruc]

Why does sfml use the extension .hpp? I have never before before seen that used. Also, not that I know a lot about floating-point math, but why does it use floats? It seems kind've standard in C++ to use doubles.

hpp is common... Its the header for c++.....

.h or .hpp are both C++ headers.  Double-precision math is much slower computationally and only take 4 bytes instead of 8.  Also graphics APIs are setup to deal with floats, not doubles.  Furthermore, double precision is rarely needed in graphics anyway.

most people use .h(I think), but sfml is not the only lib which uses .hpp. Another (very popular) example would be boost.
However it doesn't matter which extension they have.

I think Float matters for vram, OpenGL and DirectX both use floats, so it wouldn't make sense that sfml takes doubles and then converts them.

OpenGL uses floats.
