| What is the command for exponents. ie.How do I raise something to the nth power. I know in many languages it is ^^ but I cannot find reference to it. On the same topic can exponential notation be used. |

| You can use ^. e.g.: 2^4 = 16.0 Also, I suppose you could use exponential notation. e.g. 2*10^6 = 2 million |

| Does that work in Blitz code? I never knew that; never had to use any exponents before. |

| Yep, those are Blitz operators, and they're resolved in the correct order. Go ahead and try it. |

| Note that ^ is a higher priority than most other operators, meaning that it will be performed before multiply, divide, add, subtract, and so on. If you want to raise a value to some complex power, such as a+1, you will have to enclose the a+1 in parentheses to ensure that it gets evaluated first like so: N=b^(a+1). By definition, any value to the power of 0 is equal to 1. That is, 1=0^0 would be true. However, any value to a power of 1 is itself: 0=0^1 would also be true. And negative powers are representations of reciprocals, such that 2^(-1) = 1/2. |
