I want to ask - Why in GLSL was such design decision to make fract() function as
because it gives “incorrect” fraction values for negative arguments. Correct fract() implementation should be like this:
Anybody knows such fract() design decision ??
Thanks in advance.
Same for modulo operation, they are done differently depending on the programming language and sometimes hardware architecture :
Not sure if one is better than the other in the mathematical or design sense, anyway it will depend on what you want to do with it.
