I added the location of PIL and psycopg2 to PATH.
I know that Terminal is…

I want to pass a chunk of Python code to Python in R with something like system('python ...'), and I'm wondering if there is an easy way to emulate the python console in this case. For example, suppose the code is "print 'hello world'", how can I get the output like this in R?
>>> print…

I have a ~1000 files that when passed through this C++ program will generate ~1000 outputs. Each output file must have a distinct name.
The command I wish to run is of the form:
program_name -input -output -o1 -o2…

I just read a statement about the floating point value comparison
Floating point values shall not be compared using either the == or != operators.
Most floating point values have no exact binary representation and have a
limited precision.
If so what is the best method for comparing two floating…

In learning how floating point numbers are represented in computers I have come across the term "bias value" that I do not quite understand.
The bias value in floating point numbers has to do with the negative and positiveness of the exponent part of a floating point number.
The bias value of a…

So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did.
I understand that the computation is faster…
