What is the difference between ^ and Math.pow()

The exponential symbol can also be used for the same sake as the Math.pow func is used. Is there any difference between them and what one should prefer

^ is used as bitwise XOR operator in java, so you can't use it for raising a number to some power. lesson on XOR operator: https://www.sololearn.com/learn/4074/?ref=app

I guess in java math.pow() only works, ^ and .^ are usually used in c++, more precisely, in Matlab, there should no be difference as long as both functions to calculate the power of an integer

in Java ^ operator is for XOR (exclusive OR) bitwise operation int a = 0b1100; // 12 dec int b = 0b1010; // 10 dec System.out.println( Integer.toBinaryString( a ^ b ) ); // 0110 bin, 6 dec

The diferrence If you use Math.pow() you still need call the class and the method of Math class. If use ^ maybe it use to giving easily way to power a number
