On page 54 of the book (not the PDF), the text says:

"Interestingly, storing an int into a float requires no work, because no data or accuracy could be lost in the process. So
220 => int myFreq;
myFreq => float myFloatFreq;
works just fine, because 220 just gets changed into 220.0, no data is lost, and accuracy is actually gained (for use later if we need it)."

I think you're talking about precision here, meaning that the datatype supports rational non-integer numbers.

Re: Chapter 2, page 54: accuracy vs precision
Yep. You are correct. PS: the flurry of my replies here
is because I've been in Africa for a few weeks. Back in
the saddle now, and ready to start finishing up this book !
