[Jprogramming] Round to integer

[Linda A Alvord]

I even had lousy data with no negative integers in test (I'm asshamed)

   ]N=:-50-100*?4 5$0
0.773157  20.5198   15.902 _35.0173  15.9508
 _34.929 _48.6306  46.9605 _1.52882  46.3141
 20.9279 _47.5387 _29.5731 0.816917 _22.7251
 40.8983 _25.4991  _32.985 _47.5215 _19.0724

(but code still worked except for qaussian numbers)

Nice Kip, Linda

Hmm.. clearly not intended for gaussian integers.

   ri =: * * [: <. 0.5 + |
   ri 1j1
0.707107j0.707107

But I guess that's the thing about what we get taught... it tends to have only situational relevance.

Thanks,
