cailculato-hp-11C (5)

The HP-11C was a mid range scientific programmable calculator. Compared to the previous series it would fall between the HP-33E/C and HP-34C. It also included two new features: a built-in random number generator and a backspace key that allowed numbers to be corrected a digit at a time.

Non-Programmable Features

Compared to the HP-10C, the HP-11C also included:

  • Hyperbolic and inverse hyperbolic trig functions.
  • Probability (combinations and permutations).
  • Factorial, % change, and absolute value.
  • And, as mentioned above, backspace and a random number generator.
