• abs()

  returns the absolute value of a numerical value.
• acos computes the arc cosine of a value.
• asin() calculates the arc sine of a value.
• atan computes the arc tangent value.
• cbrt returns the cube root value to a double data type.
• ceil, which returns the smallest (closest to negative infinity) double value that is greater than or equal to the specified argument and is equivalent to a mathematical integer.
• cos returns the trigonometric cosine of an angle.
• cosh returns the double value of the hyperbolic cosine.
• exp returns Euler’s number raised to the power of a double value.
• floor, which returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equivalent to a mathematical integer.
• hypot, which returns sqrt(a^2 + b^2) without intermediate overflow or underflow.
• IEEEremainder computes the remainder operation on two arguments as prescribed by the IEEE 754 standard.
• log returns the natural logarithm (base e) of a double value.
• log10 returns the base 10 logarithms of a double value.
• log1p, which returns the natural logarithm of the sum of the argument and 1
• max returns the greater of two numerical values.
• min returns the smaller of two numerical values.
• pow returns the value of the first argument raised to the power of the second argument.
• random generates a random double value between 0.0 (inclusive) and 1.0 (exclusive).
• round(double num), which returns the closest long to the argument.
• round(float num) returns the closest int to the argument.
• sin returns the trigonometric sine of an angle.
• signum, which returns the signum function of the argument.
• sinh returns the hyperbolic sine of a double value.
• sqrt returns the correctly rounded positive square root of a double value.
• tan returns the trigonometric tangent of an angle
• tanh returns the hyperbolic tangent of a double value.
• toDegrees converts an angle measured in radians to an approximately equivalent angle measured in degrees.
• toRadians converts an angle measured in degrees to an approximately equivalent angle measured in radians.
• E represents the base of the natural logarithms.
• A String variable is a class type variable that can name an object, and an object has methods as well as a value. These String methods can be used to manage string values
• equals(Other_String) – returns true if the calling object String and the Other_String are equal. Otherwise, it returns false. callingString.equals(Other_String)
• length() – returns the size of the String objec
• equalsIgnoreCase(Other_String) – returns true if the calling String object and the Other_String are the same, considering uppercase and lowercase versions of a letter to be the same. Otherwise, it returns false.
• toLowerCase() – returns a string with the same characters as the calling object String, but with all characters converted to lowercase.
• oUpperCase() – returns a string with the same characters as the calling object String, but with all characters converted to uppercase.
• trim() – returns a string with the same characters as the calling object String, but with leading and trailing white space removed.
• charAt(Position) – returns the character in the calling object string at the position. Positions are counted 0, 1, 2, etc.
• substring(Start) – returns the substring of the calling object String from Position Start through to the end of the calling object. Positions are counted 0, 1, 2, etc
• subString(Start, End) – returns the substring of the calling object String beginning Position Start through, but not including the End position of the calling object. Positions are counted 0, 1, 2, … etc.
