Features of the real HP-15C
The HP-15C was a high end scientific programmable calculator and the top model of the Voyager series. Some of the main features are:
- RPN logic with 4 stack levels plus a last X (LSTx) register.
- 67 addressable registers, used for storage registers or program steps.
- 19 storage registers in default configuration with 46 registers for programs (appx. 332 program steps).
- Programmable with up to 448 program steps. In this configuration only 3 storage registers are available: R0, R1 and RI
- 10 Flags and 12 conditional tests, such as x = 0, x ≠ 0 and x > y.
- Indexed looping via storage gegister I.
- Full storage arithmetic: STO +, −, × and ÷.
- 5 softkeys, labeled A through E.
- Multiple number format: FIXed, SCIentific and ENGineering.
- Trigonometric functions SIN, COS and TAN.
- Hyperbolic trigonometric functions SINH, COSH TANH.
- Three trigonometric modes: DEGrees, RADians and GRADs.
- Reverse trigonometric functions for standard and hyperbolic functions.
- Mean and standard deviation of 2 variables.
- Summation of n, x, x2, y, y2 and xy for statistic calculations of 2 variables.
- Decimal hours and hrs.min.sec. conversions.
- Polar and rectangular conversions.
- Solve and root finder.
- Numeric integration.
- Linear regression.
- Complex numbers.
- Matrix operations.
- Continuous memory.
