Hey everyone, I make a moneysupply calculator type thing with an app called Codea (ios).

This is what the moneysupply is today.

I should make it so that it takes the date and time and gives you a live reading.
(right now it just goes up 1 day/second)

I figured out how I can remove the extra decimals from the blockreward.

roundedblockreward=blockreward*100000000

math.ceil(roundedblockreward + 0.5)

roundedblockreward=roundedblockreward/100000000

Then I used roundedblockreward instead of blockreward. (otherwise it decreases the blockreward faster.

Ok, fixed reward halvings to be every 2 000 000 blocks instead of 2 102 400.

I am also trying to understand this line in main.cpp;

nSubsidy -= nSubsidy*(nHeight % g_RewardHalvingPeriod)/(2*g_RewardHalvingPeriod);

What does -= mean? Does it mean nSubsidy=nSubsidy-*(blah blah blah?

Also, what does the % do?

Is this the same as:

nSubsidy=nSubsidy-((g_RewardHalvingPeriod/2)/g_RewardHalvingPeriod)

I am trying to reduce nSubsidy for each block in my calculator.

What does this whole thing mean;

Code: [Select]

int halvings = nHeight / g_RewardHalvingPeriod;
nSubsidy = (halvings >= 64)? 0 : (nSubsidy >> halvings);
nSubsidy -= nSubsidy*(nHeight % g_RewardHalvingPeriod)/(2*g_RewardHalvingPeriod);

Code: [Select]

nSubsidy = nSubsidy - (nSubsidy*(nHeight % g_RewardHalvingPeriod)/(2*g_RewardHalvingPeriod));

Thanks, but what is the %?

a -= b means a = a - b.
% is the modulo operation.
>> is a right bit shift, it multiples number to the left to the negative power of two of the number to the right.

Ah ok, The modulo operation is the remainder when dividing the left number by the right number, right?
I'll fix my calculator with that modulo operation.
I also need to reprogram the graph rendering. It'll be done in the next few days. But its not like anyone cares anyway. :/

It's not over until it's over. I care.

Wow, weirdest thing just happened. I was JUST reading this topic and you replied.
Thanks for the encouragement. You too pokeytex.
