Correct way to transfer ERC-20 tokens and keeping decimals in count?

Question

I have a token with 18 decimals, I'm using the OpenZeppelin StandardToken example and have figured out that when I want to send value I have to keep the decimals in count as such: _value * 10**decimals.

uint decimals = 18
transfer(_receivers[i], (_amount[i] * 10**decimals));

This will send the correct amount of tokens. But I don't want to calculate the decimals every place I use the transfer function.. Is it frowned upon to change the OpenZeppelin transfer() function to set the value there to

_value *10**18

Or is there an other way that is better?

Answer 1

You can just create a temporary variable and calculate the product before passig the value to the trasnfer function. There is not problem doing that.

Hope this helps
