RE: WP 34S --> WP 31S
I just downloaded the wp31s emulator from: http://sourceforge.net/p/wp34s/code/HEAD...hes/wp31s/
and discovered a small error in the "sin" function and the "To Rectangular" function (because it uses the sin function). With the calculator in degrees mode if you take the sin(90) or sin(270) the sign of the returned value is inverted. sin(90) returns -1 (not +1), and sin(270) returns +1 (not -1). This also affects the "to Rectangular" function which uses the sin function. The sign of the returned result is incorrect for all angles between 90 degrees and 135 degrees, and for angles between 270 degrees and 315 degrees. All other angles return the correct result, and it seems that in radians mode all angles return the correct result. Also I noticed that when you press "f mode" and try to select ssize8 the stack size stays at size 4. Thanks for building another calculator, I realize that there will be plenty of tiny mistakes initially. Keep up the excellent work. |
