Basic data specified on programmable calculator intended for currency calculations under stochastically indeterminate external economic environment. Calculator estimates deposit efficiency by such schemes: deposit placement in national currency without conversion; deposit placement in foreign currency with double conversion. Calculations are effected using interval and Euclidean arithmetic. Calculations are performed on the basis of classic axiom system of interval arithmetic, Kaucher axiom system and non-standard axiom system.
