What is the "to the power of" symbol in objective-c

Question

For the program I am making, I need the to power of symbol, but when I try to use the general symbol (^), it doesn't recognize that?

Could anyone tell me what symbol to use instead?

Answer 1

there is no pow symbol. use the C function pow(x,y);

double res = pow(5.0,2.0); //25
