• A flexible work area lets you type in your calculations directly. It is as simple as a regular text editor, and you can further process your results the same way.
• Financial functions: future value, present value, interest rate and more.
• Exponentials functions: exp, ln, log, fact, pow, root and more.
• Fractional and whole number processing: ceil, floor, round, sRound and more.
• Random number generation, real or complex, linear or gaussian.
• Seven different numeric formats for all needs: scientific (1.23e-45), currency (12,345.00), fractional (1 2/3) and more. Each one of these formats is customizable.
• Prime number functions.
• Trigonometric and Hyperbolic functions, normal and inverse.
• Statistical functions: group attributes (max, gcd, lcm and more) and distribution values (sd, var, median and more).
• Bit-level binary functions: binary-and, binary-or, binary-shift and more.
• Units and conversions: meter -> foot, ounce -> gram, liter -> pint, day -> minute, C -> F and many more.
• Numeric bases: binary, octal, hexadecimal, in fact all number bases from 2 to 36 are supported in all functions and all display formats. Easily convert from any numeric base to any other.
• Complex numbers are natively supported and also accompanied by a specialized set of access functions.
• Annotate, edit and repeat your calculations in the work area. Save your work for later use: select either a text (.txt) or rich-edit (.rtf) document, restore it, email it, edit it with a word processor, etc.
• Comprehensive online help is included. You'll need it given all these features.

Looks best with Windows XP in 800x600 (or better) and 32-bit colour. Includes support for Windows Vista.

Portable Version also available.

Developed using ESB Professional Computation Suite for VCL - ESB Professional Computation Suite and LMD-Tools.

ESBCalc Pro is an Enhanced Windows Scientific Calculator with Infix Processing, Exponential Notation, Brackets, Scientific Functions, Memory, Optional Paper Trail, Printing, Result History List, Integrated Help and more. Functions include Trigonometric, Hyperbolic, Logarithmic - Base 10, Base 2, Natural - Random Number and many more. Also includes heaps of built-in as well as user-defined constants, Hexadecimal Conversions and Fraction Conversions. Also allows for Floating Decimal Point, optionally start at last position and other improvements to the User Interface.

The calculator can have Prefix Functions turned on so that when calculating log (25), you can enter log 25 rather than the traditional 25 log.

The Calculator also has an expression editor that allows the data that has been entered can be then edited and recalculated. Plus you have a dialog that supplies descriptive statistics such as Mean (Average), Median, Variance, Standard Deviation, Skew and Kurtosis. Plus it can now also calculate the time between two dates and/or times.

Precedence can be turned off for those who do not wish it.

Optimized for Windows XP/Vista/7 in 800x600 (or better).
