Submission Details
Severity:
wrongly calculating interest in _calculateInterest function
Summary
Interest calculated for an loan is wrongly calculated.
Vulnerability Details
using simple interest formula PTR/100
where
P = debt
T = timeElapsed
R = interestRate
but an year doesn't always have a 365 days. So the final calculated interest is wrongly calculated.
On leap years, the number of days is 366, so calculations during those years will return the wrong value
