com.api.jsonata4java.expressions.functions.SqrtFunction

public class SqrtFunction
extends FunctionBase

http://docs.jsonata.org/numeric-functions.html $sqrt(number) Returns the square root of the value of the number parameter. If number is not specified (i.e. this function is invoked with one argument), then the context value is used as the value of number. An error is thrown if the value of number is negative. Examples $sqrt(4)==2 $sqrt(2)==1.414213562373
