Function: isqrt (<x>) Returns the "integer square root" of the absolute value of <x>, which is an integer.

max: 230;
range: 27;
multiplier: 12;
isqr: max/(multiplier*(x/range)^2+1);
ilin: max/(multiplier*(x/range)+1);
isqrt: max/(multiplier*sqrt(x/range)+1);
plot2d([isqr,ilin,isqrt,100,max*(1-(x/range))],[x,0,range],[y,0,max]);
float(solve(100=isqr,x));
float(solve(1=isqr,x));
float(solve(100=ilin,x));
float(solve(1=ilin,x));
float(solve(100=isqrt,x));
float(solve(1=isqrt,x));
