The only tolerance in the computation is from the usual tolerant comparison.
Addition isn't associative either, you know. Henry Rich On 5/15/2020 7:03 PM, Raul Miller wrote:
It is odd, though, that even with comparison tolerance set to zero, +. is not associative on fractional floating point values: 9!:19]0 0j16":,.+./4.57 4.34 4.44 0.0000000000000036 0j16":,.+./|.4.57 4.34 4.44 0.0000000000290870 It is commutative though: (-:|:)+./@>{;~4.57 4.34 4.44 1 0j16":+./@>{;~4.57 4.34 4.44 4.5700000000000003 0.0100000000000655 0.0099999999999758 0.0100000000000655 4.3399999999999999 0.0200000000000466 0.0099999999999758 0.0200000000000466 4.4400000000000004 I'm not quite sure what's going on here... maybe a built in epsilon which is independent of comparison tolerance?
