About N in Mathematica 4
Hi! I've a question about the function N in Mathematica 4. I haven't found information about this problem. The question is: why if I use N[Pi,30] I'll have a number of 30 decimal digits, but with N[Pi,10] or N[Pi,3] I'll get a number of 6 digits? The right number of digits is given only if I use a precision bigger than the precision of the machine. But if I want a number of 3 decimal digits? Thanks.
