The algorithm uses a 32-bit floating-point arithmetic, and is based on a digit-by-digit iterative computation that does not require look-up tables, curve fitting, decimal-binary conversion, or division operations; the number of iterations depends on the precision defined by the user.
Given that the decimal digits of π are essentially random, I could have started from any of the 10244 possible sequences of 244 decimal digits, and with similar effort could have constructed an étude that would presumably be about as convincing musically as the one based on the digits of π.
The measurement technique we used is found to correlate quite strongly with bone lengths (Leoni et al. 2008), and thus, estimates of digit ratios based on whole digits largely convey the same biological information as those based on exact bone lengths.
We know that our Service Provider will deliver five digits in the called party number so we match based on five digit numeric values.
Data on attitudes, knowledge, situational awareness, risk perception and preventive behaviours (Table S1) were collected by household telephone interviews, based on random digit dialling.
