What am I doing wrong here - canFind with iota is not working

also mark your float litteral with the f postfix. By default FP 
litterals are double...IIRC

float oneDegree = (PI / 180.0f);
float first = -(oneDegree * 10.0f);
float second = (oneDegree * 10.0f);
float step = 0.000001f;
float[] r = iota(first,second,step).array;

writeln(r);

float item = 0.174531f;
writeln(r.canFind(item));
