MathGV Function Plotting Software

Features in MathGV 3.1

MathGV is a software program designed to generate graphs of mathematical functions. It can not plot raw data points. It can plot functions only.

1. Plots 5 function types; 2D Cartesian (X, Y), parametric, polar, 3D Cartesian (X,Y,Z), 2D function rotated into 3 dimensions.
2. Graphs can contain multiple functions.
3. All graphs are drawn on resizable bitmaps, and displayed in scrolling windows.
4. Graph bitmaps can be copied and pasted into other programs, or saved to disk.
5. Multiple document interface (MDI) allows for simultaneous viewing of multiple graphs.
6. Can calculate negative numbers to fractional powers.
7. Function calculator that can give decimal or fractional results.
8. All changes take effect immediately after they are made.
9. Use tool bar buttons to zoom, rotate, and page up, down, left, right.
10. Graphs can be saved in bitmap (bmp), jpg or MathGV format.
11. Label tool bar for drawing, lines, free hand lines, rectangles, circles, round rectangles, flood fills, and text.
12. Labels can be selected, dragged, dropped, resized, added and deleted on any graph at any time.

Bug Fix and Improved Accuracy in Version 3.1

Bug Fix
Version 3.1 contains a fix for a minor bug that was in version 3. This bug affects negative number to fractional power calculations like "(-8)^(2/3)". This example evaluates to "-4" but the correct answer is "4". This bug only appears if the numerator is even (2) and the denominator is odd (3) and the base number (-8) is negative.

Improved Calculation Accuracy
Version 3.1 can produce an exact fractional result for numbers with larger numerators or denominators. In version 3.1; Fractions where the numerator or denominator is bigger than 1.5 trillion can cause rounding. The old limit was 10 billion.

Larger program file will not fit on a floppy disk
Version 3.1 has grown to 1.5 megabytes and will no longer run from a 1.4 megabyte floppy disk.
