    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

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
