Hey All, How do you use KDB sin/cos/tan to solve for the angles of a
triangle? Im not asking about SOHCAHTOA -- when I use the sin/cos/tan
functions in KDB/q I get different results compared to other language's
functions. Is there a conversion im mis...
Greetings All, I've got a couple 40gb CSVs that I'm hoping to perform
some joins on. I do not know the column format, or headers, or if
headers are even in the csv. Im working with a good bit of memory, with
256gb accessible. Loading the files into m...
Hey David, thanks for the help! I'm dealing in degrees, or trying to.
Does kdb sin/cos only accept radians? For example, if I go sin(30) on my
comp calc i get .5. When I go sin(30) in kdb I get -0.9880316. At it's
simplest form, I'm trying to use the...
Longstory short I have a dump file that I converted to txt file. When I
read it into kdb its all 1 line and you can tell the columns are split
by single backslash. Thusfar all my attempts at opening/tabling this pig
have failed. I apologize for the p...
Hey David, thanks! Unfortunately that didn't split the backslashes for
me. I guess to be more specific, the file is columns of data smushed
together with a backslash to delimit them. I'm trying to get this all
into a table. Is there no way to use a "...
