hello
i try to divide 2 variables in order to get a percentage--that's why i'm not interested in integer division--but nothing seems to work
I think awk is suitable for this but i'm not quite sure how to use it..
any ideas?
here's what I want to do:
percentage = varA/varB
thank you (2 Replies)

gsl-randist
GSL-RANDIST(1) General Commands Manual GSL-RANDIST(1)
NAME
gsl-randist - generate random samples from various distributions
SYNOPSYS
gsl-randist seed n DIST param1 param2 [..]
DESCRIPTION
gsl-randist is a demonstration program for the GNU Scientific Library. It generates n random samples from the distribution DIST using the
distribution parameters param1, param2, ...
EXAMPLE
Here is an example. We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range -100
to 100, using 200 bins.
gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat
A plot of the resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample
size.
awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X
SEE ALSO
gsl(3), gsl-histogram(1).
