- 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 + 1SurdText[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 LaTeX Formula box needs to be enabled in the Properties dialog box 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.
