SurdText Command

SurdText[ <Number> ]

Creates text representation of the number in the form \frac{a+b\sqrt{c}}{d}

Examples:

• SurdText[2.414213562373095] creates \sqrt{2} + 1
• 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}.

Note: Because this command works with a rounded decimal number as the input, sometimes the result will be unexpected.

Note: If a suitable answer can't be found, the number will be returned. For example SurdText[1.23456789012345].
