Does the new 15c ce utilise IEEE754 floats?

[Nigel (UK)]

IEEE754 supports both binary and decimal bases; Free42 on the DM42 is the decimal version, so it should be all right.

On a non-symbolic calculator, sin pi won’t be exactly zero, because 3.141492654 isn’t exactly pi. So a non-zero answer isn’t necessarily a problem.

I don’t have a HP15-ce, but I believe it runs the original HP15c microcode, which has an excellent reputation.
