Sailing in rough sea (for those who do not suffer from seasickness) #sea #water

u/cantelope

awesome progression and artistic purposing of this function :)
u/joeytwiddle

What's going on here? How can you use bitwise not (~) on a floating point number?
u/joeytwiddle

Oh, it looks like ~ makes the number negative, and then rounds it down
u/joeytwiddle

So with n+~n+.5 you get a sawtooth in the range -.5 to +.5, based on the fractional part of n
