 Many existing expressions were also significantly optimized (2-3x speedups) by avoiding memory copies and leveraging 
 Arrow format’s invariants.

+Unary mathematical functions (such as sqrt) now support both 32 and 64-bit floats and return the corresponding type, 
 thereby allowing faster operations when higher precision is not needed.
