Dear all,

In a cam profile generation program, I perform some boolean operations with angular values (input in degrees).
I noticed some boolean operations fail due to a varying accuracy.
The file in attachment will clarify what I mean.

How can I make these values equal? Reduce the amount of significant numbers?

Thanks in advance for any feedback!

Kind regards,

Jan

If numerical arithmetic can't ... You can't.
Visit the previous thread in the Forum.

Choose symbolic optimization in the matrix definition.



Best regards.

Leave the main matrix numeric, explore Numeric/Symbolic in-situ
The two Boleans disagree ... IMHO, Numeric is the practical procedure.
