function splitAmount(uint256 amount) private {
a1.transfer(amount.div(2));
a2.transfer(amount.div(2));
}
I've seen other threads on this but I feel like over complicate things. With this code the amount is evenly split between a1 and a2 with division by 2.
How would one do something like a 80/20 split with the same code?
80% is the same thing as
divide by 100, and then multiply by 80
as well as
divide by 5, and then multiply by 4
a1.transfer(amount.div(5).mul(4)); // 80% of `amount`
You can simplify the 20% in the same way:
divide by 100 and then multiply by 20
which is
divide by 5, and then multiply by 1
which is simply
divide by 5
a2.transfer(amount.div(5)); // 20% of `amount`
