[SDL] Plotting

[naman kohli]

yeah but what i am asking is that lets say i calculate a sin x value which
is floating.Now i need it to be mapped to a pixel.What should I do. Like if
I simply round it all values would be the same.
I need a function that simply does this so i can use it in a recursive
manner to calculate sin(cos(x)) etc...
