ExCalc - History of Development Changes
Copyright  2000-2001 by Tek Design

V. 2.02 (February 12, 2001)
1. Operands *, / and ^ followed by + or - without brackets can be
  correctly recognized. ExCalc understands 3.14*-2, 3.14/-2 and
  3.14^-2 as 3.14*(-2), 3.14/(-2) and 3.14^(-2) respectively.
2. A comment can be added to custom functions such as "Quadratic
  formula:{X+sqr(X^2-4*Y*Z)}/(2*Y)" placing a colon between the
  comment and the equation.

V. 2.01.18 (October 29, 2000)
1. When large fonts were used for Windows system, the main form and
  the About dialog box were incorrectly shown. This bug was fixed.

V. 2.01.17 (October 21, 2000)
1. Minor change for dynamic data exchange with SuperCon 2000.

V. 2.01.12 (September 2, 2000)
1. Custom functions which include exp() like 1-exp(0.123*X):4.567
  resulted an error. This bug was fixed.
2. Custom functions can now contain up to three variables. For example
  {X+sqr(X^2-4*Y*Z)}/(2*Y):8.753:1.85:1.577 gives 4.543745686, which
  means {X+sqr(X^2-4*Y*Z)}/(2*Y)=4.543745686 for X=8.753, Y=1.85 and
  Z=1.577.

V. 2.01.11 (August 20, 2000)
1. Custom Functions like {X+sqr(X^2-4*8.753*1.577)}/(2*8.753):8.753,
  where X is a variable, can now be added and evaluated.
2. The abbreviations for some special values, such as the ratio of the
  circumference of a circle to its diameter (pi) and the conversion
  factors to the metric units (from pound, pound-force, gallon [U.S.],
  gallon [U.K.], Btu[IT], Btu[th], calorie [IT], calorie [th], mile,
  yard, foot, inch, knot, horsepower, etc.), can now be used.
3. Either a dot (".") or a comma (",") can be used as decimal
  separator regardless of the number locale of the operating system.
  This modification was made because some european customers reported
  their num pad enters dots though the Window system uses a comma as
  decimal separator.
4. The range of significant figures was increased.
5. The appearance was a little bit modified.

V. 1.02 (June 25, 2000)
1. When you click the OK or the Cancel button in the Fonts and Colors
  dialog box, the ExCalc window cannot stay on top even if you chose
  the Always on Top option. This bug was fixed.
2. The previous evaluation history and the last math expression can be
  restored when you run ExCalc.

V. 1.01 (May 1, 2000)
Original release.
