Float precision between windows and mac.

Unity Engine
1

Hi all,

im having troubles with vector3 float precision between mac and windows. ive made a test scene, with a rigid body sphere in a empty box, that receives a relative force to bounce freely inside the box,
and im printing the position along the time to compare if igot the same result in mac and windows, and the result were catastrophic, i got precision error in less than 1 second, what gives me a huge difference in long simulations. :frowning:

in first second on mac i got : (0.1149546; -2.80927; -0.2053944)
and in windows i got these : (0.1149545; -2.80927; -0.2053942)

i`m using the fixed update, but even without adding any force, just letting the gravity do the job i got the same precision error. :expressionless:

Does any one know how can i handle this precision issue?

thanks any way!

you have error in 7th digit - it is kinda the nature of floating point :wink:
though we are looking into making it better in next release
