**Note:** Function and constant names are not case-sensitive. For example, Exp *is the same as* EXP or exp. The variable, which is the letter "x", is also not case-sensitive.

**Note:** Up to ten equations could be plotted at the same time, so that intersections and domains could be studied visually.

**Note:** Text after proper mathematical expression, will be ignored by the compiler. You can use this feature to comment your equation set.

**Note:** In particular, you cannot use ^ for exponentiation, you must use the Power function instead.

**Note:** All the algebraic, trigonometric, hyperbolic and transcendental routines map directly to Intel 80387 FPU floating point machine instructions.

**Note:** As operands you can use numeric constants in any form (2, 2.0, 2e5, 2e-3) with decimal delimiter "period" or "comma", depending on your computer system configuration.

2. Example of formula: (2.0e-3*x) + square(x) + power(x;3) + power(2.55;4) + logbaseN(4;6.25)

Thus! If your computer system configuration uses "comma" as decimal delimiter/separator, 2.55 in the above example must be 2,55

Example of formula: (2,0e-3*x) + square(x) + power(x;3) + power(2,55;4) + logbaseN(4;6,25)

4. Edit-box "Step": The smaller value it has, the more accurate drawing you get.
