trigonometric functions

[s2iYlee]

Hello. 

I found that the result of sin() or cos() is different depending on the CPU.

Please refer the capture below.

Intel(R) Core(TM) i7-2700K CPU @ 3.50GHz 3.50 GHz

Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz 3.40 GHz

[Right]

Intel(R) Core(TM) i9-10900X CPU @ 3.70GHz 3.70 GHz

It seems the older generations of CPU work differently.. is it correct?

Can anyone explain why this problem occurs?

Can anyone list the types of CPU that works differently?
