SurdText Command

SurdText( <Point> ): Creates a text representation of the point, with coordinates in the form $\frac{a+b\sqrt{c}}{d}$ .

SurdText((2.414213562373095, 1.414213562373095)) creates the text ( $1 + \sqrt{2}, \sqrt{2})$

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

SurdText( <Number>, <List> ): Creates a text representation of the number, rewritten as a multiple of the constants in the list. If the list is empty, the command uses a list of common constants.

SurdText(3.718281828459045, {exp(1)}) creates the text $e + 1$
SurdText(5.382332347441762, {sqrt(2), sqrt(3), sqrt(5)}) creates the text $\sqrt{5} + \sqrt{3} + \sqrt{2}$
SurdText(1.693147180559945, {ln(2)}) creates the text $\ln(2) + 1$

In order to use this command in a Text object, the option LaTeX Formula needs to be enabled in the Text tab of the Properties Dialog of the text.
Since this command works with a rounded decimal number as input, in some cases the result might be unexpected.
If a suitable answer can’t be found, the number will be returned. For example, the command SurdText(1.23456789012345) returns 1.23456789012345.
