| Dec 16, 2023 at 19:52 | comment | added | Nick Kennedy | The result for a=0 should be 6; the 0.5 diameter circle only fills about 39% of the top-left grid square | |

| Dec 16, 2023 at 16:42 | comment | added | Graham | Following my previous comment about symmetry and given your explanation why square 4,4 should not be included should square 3,3 on the grid diagonal be included to give us 11 squares with the answer dropping back to 4 | |
| Dec 16, 2023 at 16:15 | comment | added | Simd | @user1502040 Thanks, fixed. Could you double check my second example please. | |

| Dec 16, 2023 at 16:08 | comment | added | user1502040 | I think 'd' and 'x' are confusing names. Use 'r' for the radius, and maybe 'a' for 'x'. | |

| Dec 16, 2023 at 15:17 | comment | added | Graham | Is this not a symmetrical problem about the diagonal of the grid. If so should there not be 10 qualifying squares in your first example viz. 1, -1, 3, 3, 2, -1, 1, -3, -1, 1 giving a total of 5 | |
| Dec 16, 2023 at 13:01 | comment | added | l4m2 | No but I stop here and ask ChatGPT instead | |
| Dec 16, 2023 at 12:30 | comment | added | Simd | @l4m2 If the circle goes directly though the midpoint and it is one of the squares at location (i, i) (that is on the diagonal) then the square is not half covered. Does that answer your question? | |
| Dec 16, 2023 at 12:26 | comment | added | l4m2 | I mean circle cover midpoint but not half covered | |

| Dec 16, 2023 at 12:19 | comment | added | l4m2 | Is there counterexample where [midpoint included] xor [half in]? | |

| Dec 16, 2023 at 11:28 | comment | added | Simd | @LevelRiverSt I have made the input clear I hope. I'll add a comment about numerical accuracy m | |

| Dec 16, 2023 at 10:43 | comment | added | Level River St | Is d guaranteed to be an integer, or can it be any real number? Also, what is the margin of error? is it acceptable to incorrectly include a square with 49% or 51%? That will make a huge difference to the length of the code. It would be much easier if we could include all squares that have any part of the circle in them. | |
