Zero-decimal currencies
Most currencies have a smallest unit worth one hundredth of the major unit, like a cent of a dollar. A handful do not, and SadAnalytics scales those differently so the figures on screen stay correct.
What a zero-decimal currency is
A zero-decimal currency has no fractional subunit worth using: its smallest unit already is one whole unit, unlike a currency such as USD where the smallest unit is a cent, one hundredth of a dollar. SadAnalytics recognizes sixteen of them:
- JPY (Japanese yen)
- KRW (South Korean won)
- VND (Vietnamese dong)
- BIF (Burundian franc)
- CLP (Chilean peso)
- DJF (Djiboutian franc)
- GNF (Guinean franc)
- KMF (Comorian franc)
- MGA (Malagasy ariary)
- PYG (Paraguayan guarani)
- RWF (Rwandan franc)
- UGX (Ugandan shilling)
- VUV (Vanuatu vatu)
- XAF (Central African CFA franc)
- XOF (West African CFA franc)
- XPF (CFP franc)
How SadAnalytics scales them
Internally, SadAnalytics stores every amount as a whole number in the currency's smallest unit, the same way Stripe does. For an ordinary currency that number is divided by 100 before it is shown, since 100 cents make a dollar (or euro, or pound). For a zero-decimal currency, SadAnalytics divides by 1 instead: the stored number already is the amount in whole units, so nothing is scaled down and no decimal point is added.
This matters mainly if a figure ever looks off by a factor of 100. If a figure in one of these sixteen currencies looks 100 times too big or too small, email me at [email protected]. That is a bug, and I will fix it.
Where this shows up
The clearest place to see it is Target MRR in Settings, then General: on a JPY site, typing 500 sets a target of five hundred yen, not five hundred yen's worth of cents. Every other currency field behaves the same way: for a zero-decimal currency, the number you type or read is already the whole amount.
Currency conversion is unaffected by any of this: a zero-decimal currency still converts to your primary currency at the current exchange rate exactly like any other currency; only the scaling of its own smallest unit is different.
