Hi,

Can someone please repeat and/or explain the IDL DOUBLE() results below?
This is a copy of an IDL 5.2 session on a Silicon Graphics O2 running
IRIX 6.3, IDL 5.2 on a Digital PW 500a running Digital UNIX 4.0D gave
the same results... Thanks a lot for the help,

Jacco

PS Please remove the .NOSPAM from my mail address when replying.
