使用NSIS Math Library：如何执行'Power to'

Question

我正在尝试使用NSIS Math Library执行Power计算。我在编写Math库语法方面遇到了很多困难。

如何在NSIS中执行此计算：h ^= g;

Var h # example variables
Var g
Var a

# I am attempting to perform the following calculations in NSIS.
# I'm not sure how exactly to do it using the math library syntax?
# Do I need to include the Math.nsh library to use it?
# h ^= g;

# My attempt:
Math::Script "a = $h; b = $g; c = ?? a = Power(a,b,c); R0 = a"

Answer 1

它与C / C ++非常相似，定义一个计算XOR并返回结果的函数，试试;

Math::Script 'myxor(h,g) (h^g);'

之后，myxor（3,2）会给你3 XOR 2 = 1。
