RPN-45 HD|生產應用線上App不用買-HotApp4Game

RPN-45 HD is a complete simulation of the scientific hand-held calculator HP-45 from 1973. Processing times and behavior have been carefully modelled after the original. Switch to the "Super-45" mode and watch the HP-45 do things never seen before.Features:• Photo-realistic look based on an existing device• Animated keys with adjustable click sound and visual feedback• All functions and operations of the HP-45 fully implemented• Supports "secret" timer. Use it as 12/100-hours timer or even as a chess clock.• Optional hyperbolic functions• Simulation of the HP-45's computation times (optional)• Correct wrong number entries by swiping left across the display• Cut/copy/paste display value• "Live" display of stack and all memory registers (in landscape mode)• Built-in manual• 30 selectable background images, even add your own• HP-91-like paper tape printer: - Supports MAN, ALL, and NORM modes - Quickly insert arbitrary text - Delete any line - Send tape via E-Mail or to any AirPrint-capable printer - Ribbon color black or blue - Optionally print negative results in red - Print stack and registersTurn on "Super-45" and enjoy a super-charged HP-45:• Complex numbers: available for almost all operations and functions• More memory: twice the number of memory registers.• "Continuous" stack and memory registers• Extended functions: - Raise any number to any power - Faculty of any number - Logarithm and square root of negative numbers - Preset timer with the iPad's real time - Chess clock mode• New functions: - Solve linear equations in two or three unknowns - Find the roots of quadratic and cubic equations - Statistics: normal distribution and correlation coefficient of paired variables - Linear regression, combinations, permutations - Integer and fractional parts - Display rounding - Random numbers in a given range - Day of the week for any date between Jan 1, 0001 and Dec 31, 9999 - Support for Julian dates - Number of days between any two dates - Last Stack - Convert display value to hexadecimal - Percentage of sum - Register arithmetic includes sum registers and LAST x• Enhanced user interface: - Visual indicators for prefix keys and angular modes - Small values switch to scientific notation if required - Localized decimal pointFor more information and sample calculations visit cuveesoft.chWHAT USERS SAID:"A great simulation of the HP-45. Beautifully made, with a lot of attention to small details.""This is by far the best RPN calculator available for the iPad!""Great app that I would recommend to anyone who grew up with an HP-45!""This is one of the most accurate but also nicest looking emulators I have come across for the HP-45, or any vintage HP calculator for that matter.""This is exactly what I've been searching. My HP 45 packed up some time ago. Thank you so much!"
