# SurdText Command

From GeoGebra Manual

- SurdText( <Number> )
- Creates text representation of the number in the form \frac{a+b\sqrt{c}}{d}.
**Examples:**`SurdText(2.414213562373095)`

creates*1 + \sqrt{2}*`SurdText(2.439230484541326)`

creates*\frac{7+3 \sqrt{3} }{5}*

- 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.
**Examples:**`SurdText(3.718281828459045, {exp(1)})`

creates*e + 1*`SurdText(5.382332347441762, {sqrt(2), sqrt(3), sqrt(5)})`

creates*\sqrt{5} + \sqrt{3} + \sqrt{2}*`SurdText(1.693147180559945, {ln(2)})`

creates*\ln(2) + 1*

- SurdText( <Point> )
- Creates text representation of the point, where coordinates are in the form \frac{a+b\sqrt{c}}{d}.
**Example:**`SurdText((2.414213562373095, 1.414213562373095))`

creates*(1 + \sqrt{2}, \sqrt{2})*

**Notes:**

- In order to use this command in a Text object, the option
needs to be enabled in the**LaTeX Formula***Text*tab of the Properties Dialog of the text. - Since this command works with a rounded decimal number as input, sometimes the result will be unexpected.
- If a suitable answer can't be found, the number will be returned.

**Example:**`SurdText(1.23456789012345)`

returns*1.23456789012345*.
