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 LaTeX Formula needs to be enabled in the Text tab of the Menu-options.svg 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.
