 | v1=1.414
 | the precision or the inexact number v1 is 4 (decimal digits);
 | but you can also write
 | v2=1.414213562373095048801688724209698078569671875376948073176679737990732478462107038850387534327641573
 | and v2 will get precision 100 (all these digits are saved into memory).

So in a Scheme implementation which has "arbitrarily big" precision,
how many digits is (sqrt 2)?  How many digits is (sin 7/5)?
