Both remainder and modulo are two similar operations; they act the same when the numbers are positive but much differently when the numbers are negative. In Java, we can use Math.floorMod() to describe a modulo (or modulus) operation and % operator for the remainder operation. See the result: | rem & +divisor| rem & -divisor …
This article show you how to use ATAN() and ATAN2() function in Oracle PL/SQL. 1. ATAN function examples The ATAN function returns the arc tangent of n, the n can be in an unbounded range. The function will returns a value in the range of -pi/2 to pi/2, expressed in radians. SELECT ATAN(1.5) FROM DUAL; …
The CEIL function round the specified number up, and return the smallest number that is greater than or equal to the specified number. CEIL function examples SELECT CEIL(1.2) FROM DUAL; — output : 2 SELECT CEIL(1.5) FROM DUAL; — output : 2 SELECT CEIL(1.7) FROM DUAL; — output : 2 SELECT CEIL(1.99) FROM DUAL; — …
The FLOOR() function round the specified number down, and return the largest number that is less than or equal to the specified number. FLOOR function examples SELECT FLOOR(1.2) FROM DUAL; — output : 1 SELECT FLOOR(1.5) FROM DUAL; — output : 1 SELECT FLOOR(1.7) FROM DUAL; — output : 1 SELECT FLOOR(1.99) FROM DUAL; — …
The ACOS() function returns the arc cosine of input n, the input n must be in the range of -1 to 1. The function will return a value in the range of 0 to pi, expressed in radians. ACOS function examples SELECT ACOS(.2) FROM DUAL; — output 1.36943840600456582777619613942212803186 SELECT ACOS(-.4) FROM DUAL; — output 1.98231317286238463861605958925708704694 …
The ASIN() function returns arc sine of input n, the input n must be in the range of -1 to 1. The function will return a value in the range of -pi/2 to pi/2, expressed in radians. ASIN function examples SELECT ASIN(.25) FROM DUAL; — output 0.25268025514207865348565743699370756609 SELECT ASIN(-.5) FROM DUAL; — output -0.52359877559829887307710723054658381405 SELECT …
This ABS() function returns absolute value of a number, for example, the absolute value of 5 is 5, and the absolute value of -5 is also 5. In Mathematics, absolute value can be think of as a distance from zero. ABS function examples SELECT ABS(-15) FROM DUAL; — 15 SELECT ABS(-51.321) FROM DUAL; –51.321 SELECT …
Java 8 introduced new methods in the Math class that will throw an ArithmeticException to handle overflows. These methods consist of addExact, substractExact, multiplyExact, incrementExact, decrementExact and negateExact with int and long arguments. In addition, there’s a static toIntExact method to convert a long value to an int that also throws ArithmeticException. Before Java 8 …
A simple Math.pow example, display 2 to the power of 8. In Math 2^8 = 2x2x2x2x2x2x2x2 =256 In Java Math.pow(2, 8) Note In Java, the symbol ^ is a XOR operator, DON’T use this for the power calculation. TestPower.java package com.mkyong.test; import java.text.DecimalFormat; public class TestPower { static DecimalFormat df = new DecimalFormat(".00"); public static …
We can use DecimalFormat(“0.00”) or BigDecimal to round float / double to 2 decimal places.
