App Review: SciPro Calculator (Apple iOS)
Title: SciPro Calc
Author: Jerry Montgomery, Digital Ambience, Inc
Price: Free (as of 1/18/2018)
Version: 1.2.5 (2017)
Portrait Orientation: Basic Calculator
In the portrait orientation, SciPro Calculator is a basic function calculator. The screen is impressive. The black display clearly shows the large blue numbers and function indicators. There is only 1 memory, but you get M+, M-, MC, and MR all on separate keys, which is nice. You can turn the AC key into an AC/backspace key in Basic mode throughout the options.
Scroll down will give you access to the calculator’s history, allowing to view and copy results, even share them by email.
Landscape Orientation: Scientific and Programmer Calculator
The calculator follows a post-fix algebraic system (think of a Texas Instruments TI-30 Xa or a Casio fx-260 II as examples). The SciPro Calculator app can handle numbers as high as 10^9864, which is very impressive.
* trigonometry and their inverses (sine, cosine, tangent)
* hyperbolic functions
* factorial, which handles all real numbers not just integers (nice!)
* logarithms and exponentials, base e, 2, and 10
* square root, cube root, power, root
* modulus (see note below)
* Two angle modes: degrees, radians
The modulus function works well on positive numbers. Comparing results using negative numbers to an HP Prime:
78 mod -11:
HP Prime: -10
SciPro Calculator: 1
-78 mod 11:
HP Prime: 10
SciPro Calculator: -1
The scientific app does lack fractions and statistics. Other than that, it’s a good standard scientific calculator.
The programmer calculator is a Boolean math calculator with four integer representations: Binary (64 bits), Octal, Decimal, and Hexadecimal. Depending on whatever mode you are in, the numeric keyboard highlights only the appropriate keys, so there is no accidently typing A in Decimal mode or 9 in Octal mode.
The ENC key turns on a unique feature, binary numbers which will give you the ASCII character, Unicode character, and the color determined by the RGB color. This is most useful when the calculator is Hexadecimal representation. You can use the arithmetic and the other functions to work with colors. Sweet!
Functions featured in the Programmer Calculator:
* Byte and Word Flip
* Bit count and shift
* Random integer
* Boolean operators: AND, OR, NOR, XOR
* 1’s and 2’s compliments (Yes, there is a difference)
The programmer calculator can handle integers as high as: 18,446,744,073,709,551,615.
Caution: No Sign Bit
Be aware that there are no sign bits with this calculator, everything is positive integer representation. Hence this why 0 – 1 returns 18,446,744,073,709,551,615 (64 1s in Binary) instead of -1.
I like the unique feature of the programmer calculator having the ability to look up ASCII, Unicode, and RGB codes. It’s a fun feature.
You probably won’t have to worry if you have to work with large numbers (at least numbers 10^100 and beyond), the SciPro Calculator app can handle it.
The blue numbers against the black screen is really nice, big, and readable, regardless of orientation of your iPhone or iPod Touch.
This is a nice calculator to have, especially for quick calculations.
