Questions tagged [exponent]

Exponentiation is a mathematical operation, written as b raised to the power of n, involving two numbers, the base b and the exponent (or power) n.

Exponentiation refers to the mathematical operation involving two numbers, one is a base and another is an exponent. It is repeated multiplication. To calculate 53 you have to multiply the number 5 (base) by itself 3 times (exponent).

Overloaded exponents C# and exponent operator

Is there a way to overload exponents in C#? I know in some languages (can't name any off the top of my head), ^ is used for exponential functions, but in C++ and C#, ^ is the bitwise XOR operator, which can be overloaded, but this is not what I want…

Determine if a number, n, is a power of some other number k. Return the exponent

Determine if a number, x, is a power of some other number y. Return the exponent. For example, for n = 9 and k = 3, return 2 because 3 to the power of 2 is 9. If n is not a power of k, return -1. I can't figure out how to return the exponent in this…

Is there a way to find numbers which is more or less than certain exponent?

I have a code writes a robot coordination in a file. Sometimes, for an unknown reason, instead of a number like 0.01845, it writes 6.92113e-310. So I'd like to filter data raised to a power greater than -12. Is there a way to achieve this in C++?

For example, since 25 and 2.2360679775 (or 5^0.5) are both powers of 5, I want the function to return 5. The only way I've found is to brute force it and just try every number. $one=25; $two=125; for($b=2;$b<=10;$b++) { $x=pow($one,1/$b); …
