How should I enter monetary values in the payment IVR?

How to type in money values using the telephone keypad

The payment service is expecting you to enter a value as though you are using an imaginary decimal point.

For example

£100.00 or $100.00 would be entered as 10000 this equates to the 100.00 in the service.

£0.50 or $0.50 would be entered as 50 this equates to the 0.50 in the service.
