This page is about a feature that is supported only in GeoGebra 4.2. |
- SurdText[ <Number> ]
- Creates text representation of the number in the form \frac{a+b\sqrt{c}}{d}
- Example:
SurdText[2.414213562373095]creates \sqrt{2} + 1
- SurdText[ <Number>, <List> ]
- Creates text representation of the number as multiples of the constants in the list. If the list is empty it uses a list of common constants.
- Example:
SurdText[3.718281828459045, {exp(1)}]creates e + 1
- Example:
SurdText[5.382332347441762, {sqrt(2), sqrt(3), sqrt(5)}]creates \sqrt{5} + \sqrt{3} + \sqrt{2}
- Example:
SurdText[1.693147180559945, {ln(2)}]creates 1 + \ln{2}
- SurdText[ <Point> ]
- Creates text representation of the point, where coordinates are in the form \frac{a+b\sqrt{c}}{d}.
Note: Because this command works with a rounded decimal number as the input, sometimes the result will be unexpected. For example
SurdText[163/ln(163)]. Note: If a suitable answer can't be found, the number will be returned. For example
SurdText[1.23456789012345].
