Discrepancies in conversion

Can mathematical rounding while converting prices to euro lead to genuine discrepancies?

Now that we have the euro as our currency, this means that all individual items purchased are priced in euro. As such, due to this conversion, there may be small differences for the total transaction value of a purchase of multiple items. For example, if you used to buy 10 stamps for Lm0.08 (€0.19), it would cost overall Lm0.80 (€1.86), but now that stamps cost €0.19 (Lm0.08) each, the total cost for 10 stamps is €1.90 (Lm0.82). Generally, these discrepancies cancel out, as it is random as to whether a price, when converted to euro, will round up or down to the nearest euro cent.

It is only in situations where multiple occurrences of the same item are purchase in high numbers that the discrepancy can become more significant. The conversion of an SMS is a prime example. The Lm0.02 converts to €0.05, so 100 SMSs will now cost €5 (Lm2.15) instead of the pre-adoption cost of Lm2 (4.66). In contrast, the Lm0.01 SMS converts to €0.02, and 100 of such SMSs will now be cheaper on euro adoption. The mobile operators also have SMS bundles available so that customers do not need to suffer the €0.05 SMS price. For example, a bundle of 300 SMS currently costs €6.99 (Lm3).
