What is the exact value of upcoming block rewards?

Question

Wrote a simple script that literally just halves 50 BTC (the initial block reward).

Are these block rewards correct or are the satoshis being rounded up/down incorrectly?

50.00000000
25.00000000
12.50000000

EDIT: Based on the total given here I think these halvings should be rounded down: https://bitcoin.stackexchange.com/a/9962/24926

Answer 1

The halvings occur in form of a bitshift operation. So, in other words, you halve and cut off. Therefore, the rewards should be rounded down.

A while back, I've generated a table with block rewards and other information.

The rewards in satoshi per block should work out to be:

5000000000
2500000000
1250000000
625000000
312500000
156250000
78125000
39062500
19531250
