WP-34S: Speed of y^x Message #1 Posted by Marcel Samek on 14 Sept 2013, 6:47 p.m. I have been playing around with benchmarking certain operations and I came across the odd fact that 1.01 ^ 1.01 executes more than twice as fast 2 ^ 2 (both using the y^x operator). I am curious as to why that is.

Re: WP-34S: Speed of y^x Message #2 Posted by Paul Dale on 14 Sept 2013, 7:31 p.m., in response to message #1 by Marcel Samek I don't have the sources to hand due to a computer crash, but I suspect this is related to the calculation of log used in this function. LN(2) is likely slower than LN(1.01). If it isn't that e^x would be my next suspect. - Pauli
