Java Math का इस्तेमाल mathematical operations के लिए करते हैं।
Java Math class की कई methods हैं जो किसी भी int (numbers), पर mathematical operations करने की अनुमति देती हैं। जैसे की elementary exponential, logarithm, square root, और trigonometric functions.
कुछ Java Math examples उदाहरण नीचे दिए गए हैं:
Math.max(x,y): method का उपयोग x और y के highest value को खोजने के लिए किया जाता है।Math.min(x,y): method का उपयोग x और y के lowest value को खोजने के लिए किया जाता है।Math.sqrt(x): method का उपयोग x का square root निकालने के लिए किया जाता है।Math.abs(x): method का उपयोग x की value की रिजल्ट को (positive) में लाने के लिए किया जाता है।
Example: Java Math
public class MyClass {
public static void main(String[] args) {
int x = 9;
int y = 15;
System.out.println(Math.max(x, y));
System.out.println(Math.min(x, y));
System.out.println(Math.sqrt(x));
System.out.println(Math.abs(x - y));
}
}
// Result for Math.max : 15
// Result for Math.min : 9
// Result for Math.sqrt : 3.0
// Result for Math.abs : 6
