RPN-34 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-34C for the iPhone. Produced from 1979 through 1983, it was the "Basil" member of the third-generation HP calculators known as the "Spice" series.
It was the first pocket-calculator ever capable of doing integration and root finding.
While the simulator works like the original calculator, a number of carefully designed extensions, along with the tremendously improved speed, make it joy to use even today.
RPN-34 CE comes with the programs of HP's "Applications", "Mathematics", "Surveying", "Student Engineering", and "Statistics" application books built-in! Handbooks may be downloaded from CuVee Software's website.
Features:
• Photo-realistic look-and-feel
• Programmable (999 steps), subroutines, 12 labels, 10 flags

• Sharing: e-mail, AirDrop, Dropbox, copy, paste, print
• 62 programs pre-installed (53 original HP)
Calculator functions:
• Integration, root solving
• Statistics (mean, standard deviation, linear regression, normal distribution)
• Factorial of any number (normal and logarithmic)
• Trigonometric and hyperbolic functions (degrees, radians, grads)
