@ldz - Not sure if the info below will help. Try the following with bx that assumes 386744892 is base 10, base16( 386744892) = 0x170D423C.
% echo 170D423C | bx mnemonic-new -l es
% echo 170D423C | bx base16-decode | ./ent -b
Entropy = 0.974489 bits per bit.
Optimum compression would reduce the size
of this 32 bit file by 2 percent.
Chi square distribution for 32 samples is 1.12, and randomly
would exceed this value 28.88 percent of the times.
Arithmetic mean value of data bits is 0.4062 (0.5 = random).
Monte Carlo value for Pi is nan (error nan percent).
Serial correlation coefficient is 0.093117 (totally uncorrelated = 0.0).
