I am trying to use Sage as a simple numerical calculator but sometimes have to fight with more advanced features, things I think are number are not. I starting using n() to fix this up, but in some cases it did not work. Bug big N N() did. Is this the way it is supposed to be ( if so why ). Identical commands ( symbols..... ) except for capitilization seems like a bad idea. Here is the code:

Is n() the same as N() if not why not

xll = 1. / ( pi * ( 2. ^ .5 ) )

xll = 22. * 2

print "xll is of type", type( xll ) print ""

print "Big N next" print N( ll )

print "" print "Little n next" print n( xll )
