上一篇博文中 电池温度检测原理和示例代码 ,由于驱动要使用对数函数而从网上参看一个实现 double ln(double a) { ; int k,nk; double x,xx,y; x = (a-)/(a+); xx = x*x; nk = *N+; y = 1.0/nk; ;k--) { nk = nk - ; y = 1.0/nk+xx*y; } return 2.0*x*y; } 尴尬的是当时内核不支持浮点运算所以停滞了, 时间紧迫只能折中先列出各个温度和电压对应表, 通过查表方式处理

Tag DirectX下的博客主要用于记录DirectX的学习过程,主要参考<DirectX 12 3D 游戏实战开发>. Vector in DirectX Shader的编写离不开数学运算,尤其是向量矩阵类型的运算,DirectX为我们准备了一个完备的数学库DirectXMath.h,里面封装了常用的向量矩阵类型,并且重载了许多方法,如点积.叉积.矩阵乘法等.DirectXMath是Windows SDK的一部分,是为D3D打造的3D数学库,采用SIMD指令集加速向量运算,如:单条SIMD
Time limit 1000 ms Memory limit 65536 kB OS Windows 中文题意 给一个数n,设将n质因数分解后可以得到 \[n=\prod_{i=1}^{\omega(n)} a_i^{p_i}\] 其中\(\omega(n)\)意思是n的不同质因子个数,\(a_i\)是n的质因子. 要求输出最小的\(p_i\). 题解 看完题解感觉很妙啊-- Let's first factorize \(N\) using prime numbers not larger
The Little Elephant very much loves sums on intervals. This time he has a pair of integers l and r (l ≤ r). The Little Elephant has to find the number of such integers x (l ≤ x ≤ r), that the first digit of integer x equals the last one (in decimal n
