Floyd Mayweather says he ain't mad at Tyga for trying to pull a gun at his birthday party over the weekend -- in fact, Floyd says the rapper will still be invited to the next big bash. 

We broke the story ... Tyga was physically removed from Floyd's 42nd birthday party at the Sunset Room on Saturday night after getting into a heated altercation with another man inside the event. 

                                 

Our cameras captured a FIRED UP Tyga as he reached into his security guard's gun holster and tried to grab the pistol. Fortunately, the quick-thinking guard snatched the gun from Tyga, preventing what could have been a deadly situation.
