Amount Regarding issue

I have one query regarding API’s implementation,
We are using square payment integration in our mobile app and I’m working in API side,
The thing is i read your documentation that if our product cost is around 4.00 GBP we need to set 400 GBP in API, is it right?
If yes then how this calculation is working we need to give this answer to our client so please help us for the same

:wave: With Square’s APIs, the amount field is always in the smallest denomination of the currency indicated by currency_code. When currency_code is GBP, the amount will reflect in pence. For example, an object priced at £5.00 will be inputted as 500 in the amount field. :slightly_smiling_face:
