Scientific Calculator DES vs HexBit

The DES-38D is an easy-to-use, multi-line Scientific Calculator with intuitive, left-to-right data entry & display. It was designed and developed by a professional engineer with a variety of features to suit the needs of engineers and mathematicians, including extensive statistical analysis & graphing capabilities. However, it is extremely simple to use and is suitable for anyone who needs an advanced calculator. The name of the DES-38D calculator comes from the fact that it utilizes base-10 arithmetic which can represent numbers with a 38-digit mantissa and an exponent range of -128 to + 127. The DES-38D is universal app that is fully functional in both portrait and landscape modes on all iPad and iPhone devices. No need to rotate to landscape unless you need a wider display area. All current and future features are included for one low price. We will never nag you for more money. KEY FEATURES: • Supports Hex, Binary, and Octal number bases in 64-bit, 32-bit, 16-bit, or 8-bit word lengths • Accepts data entry in Decimal, Scientific, or Fractional notation (& they can be mixed) • Memory and Result data can be displayed in Decimal, Scientific, or Fractional notation independently of how the equation was entered • Angle entry and computations can be performed in degrees, radians, gradians, or turns • 10 Memory Registers • 4 Display Lines: Equations, Result, current Memory Register, and Error/Information Messages • All Display Lines read in normal human, left-to-right form • The [-] key can be used for subtraction or negation as you type - no need to use the [+/-] key after the fact (although you can) • All equations are evaluated, and the Result field is updated "on-the-fly" as you enter your formula. The [=] key merely saves the equation & result to the History/Tape file • All Equations & Results are saved in a History/Tape file • Equations & Results can be recalled from the History/Tape file for reuse in other equations • Sliders to rapidly adjust Display Precision, Decimal-to-Scientific notation switching, and Decimal to Fraction notation switching • Keys for e and π plus a table with many additional scientific and mathematical constants that can easily be included in equations • Extensive built-in help screens • Copy and paste with simple tap and long touch gestures • Use swipe gestures to rapidly display all Memory Registers at once, all Constants, and the History/Tape file • Fast and simple advanced statistics functions - simply enter a data set and instantly get over 90 statistical calculations including 8 different regressions as well as a graphic plot of the regression lines • Up to 10 Statistics Data Sets with the ability to import CSV files and print, email, or share Data Sets and Calculation Results ------------------------------- LIST OF MATH & LOGIC FUNCTIONS • Add, Subtract, Multiply & Divide (of course) • Floored and Euclidean Modulus • Percentages - including Percentage, Add-On, Discount, and Ratio calculations • Square, Cube, and nth roots • Square, Cube, and nth powers • Base-10, Base-2, Base-n, and Natural Logarithms • 24 Trigonometric Functions • Combinations & Permutations • Coordinate Conversions between Polar & Rectangular • A number of Random Number Generators to simulate coin flips, dice throws, card draws and general purpose random numbers • Reciprocals • Factorials & Double Factorials • AND, NAND, OR, NOR, XOR, XNOR, NOT • Shift and Rotate Bits * Advanced Statistics with over 90 statistics values including the results of 8 different regressions plus graphing capability ------------------------- We welcome your feedback.
