J902-beta-b is available for windows/macos/linux. If you have already installed 902-beta-a, then it is easy to upgrade: load'pacman' 'upgrade'jpkg'jengine'
If you have not started with the 902 beta cycle, now is the time: https://code.jsoftware.com/wiki/System/Installation/J902 Questions, problems, etc should be addressed to the beta forum. The big advance in beta-b is the use of SLEEF library for elementary functions. SLEEF stands for SIMD Library for Evaluating Elementary Functions. For details see: https://sleef.org Compare the following in 901 and 902-beta-b: a=: ?.1e6#0 10 (6!:2) '1 o. a' 10 (6!:2) '7 o. a' The 9!:14'' result has info that is not included in JVERSION. New fields indicate the compiler and whether SLEEF is used or not. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
