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;
Hardcoding the double[] does work as expected - so why doesn't it
work with the iota generated array?
double oneDegree = (PI / 180.0);
double first = -(oneDegree * 10.0);
double second = (oneDegree * 10.0);
double step = 0.000001;
double[] r = iota(first,second,step).array;
writeln(r);
double[] hardCoded = [ 0.174521, 0.174522, 0.174523, 0.174524,
0.174525, 0.174526, 0.174527, 0.174528, 0.174529, 0.17453,
0.174531, 0.174532];
double item = 0.174531;
writeln(r.canFind(item)); // false - I expect true!!!!
writeln(hardCoded.canFind(item)); // true - as I expect
float[] r = iota(first,second,step).array;
writeln(r);
float item = 0.174531f;
writeln(r.canFind(item));
Adding the f still produces a false result. Also I tried
changing all to double but still not working - I always get
false back. Interestingly if I harcode the output of the iota
into an array - then things start to work as I expect.
