On: Which is faster? while(1) {} or while(2) {}

Time complexity is essentially the expression for computation time as a function of input size. Before you can discuss it you have to decide how you measure the size of the input. What you pick as the size of the input may vary from problem to problem and may be the list size, string length, number of penguins etc.

I wonder, how do you propose to measure the "size" of your input to bool cast?

That's why I mentioned machine precision. Bignums are going to be different and most languages don't handle big nuns or casts on them implicitly, it's mostly lib based
