Class MathFunctions

  • public class MathFunctions
extends java.lang.Object
    This class contains static methods that are place holders to register the methods of the class java.lang.Math for the BASIC programs. If the documentation of the method does not specify different then the method in this class can be invoked directly from a BASIC program and does exactly the same as the method of the same name in the class java.lang.Math.

    When a method accepts Number arguments it means that the BASIC can call the function with integer or with floating point arguments.

      • floatF

        public static java.lang.Double floatF​(java.lang.Object s)
        Convert a value to floating point. This method can be called directly from the BASIC program and it will return a java Double, that is internally a BASIC float. (Note that ScriptBasic for Java does not use float or int, only Long and Double.)

        Use this function from the BASIC program if the BASIC interpreter does not convert automatically a number to floating point but you need a floating point number and not an integer.

        Parameters:
        s - the number to convert
        Returns:
        the converted number or null, which means undefined in BASIC in case the parameter s passed can not be converted to floating point

      • integer

        public static java.lang.Long integer​(java.lang.Object s)
        Convert a value to integer. This method can be called directly from the BASIC program and it will return a java Long, that is internally a BASIC integer. (Note that ScriptBasic for Java does not use float or int, only Long and Double.)

        Use this function from the BASIC program if the BASIC interpreter does not convert automatically a number to integer but you need an integer number and not a floating point number.

        Parameters:
        s - the number to convert
        Returns:
        the converted number or null, which means undefined in BASIC in case the parameter s passed can not be converted to integer
