Like atpbx said you have it backwards. Inflation is when the value of ones money is decreased because there is more of it. Imagine if the jewelry companies around the world let loose their warehouses of diamonds and everyone now had banks of diamonds. The value of the diamond has now been inflated and therefore its value is worth less. That's what's happened to the US dollar compared to the UK pound, hence they pay 25 pounds where we pay 40 dollars.
