Hi,


I think it problem with floating point numbers. Floating-point numbers
stores numbers approximately. For example, floating-point types don't
precisely represent 0.1.

Try to use "decimal" type. Decimal type should by used in financial
calculations. You can find more information about floating-point number at:
