Calculating powers (e.g. 2^11) quickly

Possible Duplicate: The most efficient way to implement an integer based power function pow(int, int) How can I calculate powers with better runtime? E.g. 2^13. I remember seeing somewhere that it has something to do with the following calculation: 2^13 = 2^8 * 2^4 * 2^1 But I can't see how calculating each component o...

Is there an exponent operator in C#?

For example, does an operator exist to handle this? float Result, Number1, Number2; Number1 = 2; Number2 = 2; Result = Number1 (operator) Number2; In the past the ^ operator has served as an exponential operator in other languages, but in C# it is a bit-wise operator. Do I have to write a loop or include another namespace to handle...

how to combine exponents? (x**a)**b => x**(a*b)?

how to simplify exponents in equations in sympy from sympy import symbols a,b,c,d,e,f=symbols('abcdef') j=(a**b**5)**(b**10) print j (a**(b**5))**(b**10) #ans even after using expand simplify # desired output a**(b**15) and if it is not possible with sympy which module should i import in python? edit even if i define 'b' as re...

Drawing the curve y = 1 - x ^ 4 in Processing/Java

I understand that y = x ^ n would be float y = (x, n) but what if i wanted to draw the curves y = 1 - x ^ 4 y = (1-x) ^ 4 y = 1-(1-x) ^ 4 Here's the code i wrote but it doesn't draw the curve mathematically correct for y = 1 - x ^ 4 for (int x = 0; x < 100; x++) { float n = norm(x, 0.0, 100.0); float y = pow(1-n, 4); y *= 100;...
