Title: Calculating total bitcoins by number of blocks generated Post by: mizerydearia on July 22, 2010, 01:58:53 AM I couldn't find a post about this, so I created this.
freenode / #math Quote <necrodearia>http://pastebin.com/MJPr8K9d is a PHP script I wrote that calculates the output I'm looking for in http://nullvoid.org/formula.html but I would like to know if there is a one line math formula that can produce the same. <meingtsla> necrodearia: not sure about a single-line math formula, but you could do the integer division of y by 210000 (call it yQuotient) and use that to compute 210000*(50+25+...+50/2^yInt). (that's a geometric series.) then you can take the remainder of that division, call it yRemainder, and find yRemainder * 50/2^(yQuotient+1). <meingtsla> not gonna flesh it out in code myself, i'll leave that to you :p <meingtsla> sorry, wherever i said y it should be x. (integer division of x by 210000.... xQuotient... 50/2^xQuotient... xRemainder) Here's the script in action: http://nullvoid.org/bitcoin/blockcalc.php?b=1 http://nullvoid.org/bitcoin/blockcalc.php?b=210000 http://nullvoid.org/bitcoin/blockcalc.php?b=1000000 |
