Syntax

Description

Takes the square root of a positive or negative number. It works exactly the same as 2^×√ or ^(1/2) but is smaller and uses an ending parenthesis. If used on a list, it will return a list with the square root of each element.

√(4)
        2
√(2)
        1.414213562

√({1,-1})
        {1 i}

This may return a complex number or throw ERR:NONREAL ANS (depending on mode settings) if taking the square root of a negative number.

Optimization

Never raise something to the one-half power explicitly; use this command instead.

:X^(1/2)→X
can be
:√(X→X

Error Conditions

• ERR:NONREAL ANS when taking the square root of a negative number in Real mode.
