Map and Table Calculation

SQRT( ) function

Returns the positive square root of the specified input value a, i.e. Öa.

Syntax

SQRT(Value)

Input

Output

Notes:

• When the input value is negative the output value will be undefined.
• If the input value is undefined, the output will also be undefined.

Tips:

• When the output value of the SQRT function is multiplied by itself the input value is returned.
• SQRT(a) is equivalent to POW(a,0.5).
• When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.

Usable in

MapCalc, TabCalc, Simple calculators

Examples

Pocket line calculator examples:

MapCalc example:

OutMap = SQRT(InMap)

TabCalc example:
