Please note: Even if a calculator has only permissible features, it may not be used in an examination requiring an approved and labelled calculator unless it has an approval label attached. The following features are permissible in approved calculators:

• basic arithmetic functions
• basic scientific functions (trigonometric, hyperbolic, logarithms, exponents, powers, roots)
• calculation of factorials, combinations, permutations, random number generation
• calculations/conversions of/operations on numbers in non-decimal bases (e.g. binary, octal, hexadecimal)
• support for different display/calculation modes (radians/degrees, engineering/scientific, degrees/minutes/seconds, polar/rectangular)
• support for statistical calculations (standard deviation, regression, distribution values)
• support for complex numbers
• support for calculations using fractions
• built-in physical constants and unit conversion factors

Approved calculators must also have a clearly identified Manufacturer and Model Number which applies only to calculators with identical features (i.e. the same model number can't be used for two calculators which have different sets of features).

It is possible that this list may be updated over time to cover features which are not listed here.
