Trying to convert (int) for js

[EkBass]

Hi folks.

Porting some C code here for js and im now not sure am i doing it right.

The C code is as follows rx = (((int)px >> 6) << 6) + 64;

Does that (int) affect only for px in this case, or does it affect to the rest of the line? Tried to google C (int) but that only leads me to pages where data types are explained.

A cast only affects the variable immediate behind it. But rx will still be an int of course, no wider cast is needed.

Real geeky statement that is ! I can understand the shifting right and left to set the 6 rightmost bits to zero (although one would typically cast to unsigned int I think). But why you then want to add 64 is quite beyond me. I wonder if this C code will be portable to JS.

Hi cbreemer and thanks for advice.

+64 comes due assets are 64*64 pixels. This is about 3D raycasting so decimals does matter time to time.
