sin(10πx)>0;
1<=y<=2;
0<=x<=1;
sin(12πx)<0;
0<=y<=1;
0<=x<=1;
sin;(10πx)=0;
sin;(11πx)=0;
0<=y;<=2
0<x<1;

K can be described as a constant: 945223859069131854467716857603320018335217386308408527627531821152235462876323136059470692538893113823721590322264

put

To perform the principal function (print):

1. !4warning compares a portable bitmap file with a P1 magic header against K.
2. If k = K print 4.
3. else: intervals = abs(k - K) // 17
4. print(chr(intervals % 128))

You could print any other ascii by evaluating the set of files given here https://porneia.neocities.org/pbms or a zipped folder containing each bitmap can be found here. (Github)
