Give vector coordinates to three decimal places?

Lee_Hesketh

Hi is there a way to specify how many decimal places vector coordinates are because my script won't work since the coordinates are 0.3300000000000027 and not simply 0.330.

Thanks

When comparing geometric variables to one another (Vector, ValueWithUnits, Plane, Line, etc.), good practice is to use tolerantEquals, rather than the == operator. tolerantEquals simply checks whether two values are equal within our standard modeling tolerance, which is 10^-8 meters. Your numbers are well within that range, so tolerantEquals will return true.

Overloads for tolerantEquals are defined on all the standard geometric data structures in the Onshape Standard Library, including Vectors.

This is a common pain point, and in a future version of FeatureScript we intend to generate a warning when using the == operator to compare two values that are nearly equal, and suggest tolerantEquals as a solution.

For Vectors p1 and p2, you can use tolerantEquals(p1[0], p2[0])

@kevin_o_toole_1 Thanks! One question though, could I use this to check if the x coordinate of two points are equal?
