MatrixMath approximates angle

MatrixMath approximates it’s answer even though it was declared as float.
While I was multiplying a 3x3 by 3x1 mat of cos90, -sin90, 0, sin90 , cos90, 0, 0, 0, 1 by 3, 0, 1. It gave me the same ans after changing the angle to4 45 and mind you the angles were changed to radians. Pls what doy you think is wrong.

Maybe something in your code is wrong.

KAYbot: Pls what doy you think is wrong.

OK, I stop thinking and wish you to have a nice day!

Bye.
