温馨提示
多项式逼近的目录 这些文本文件报告了一些计算效率指标和准确性在Pareto前沿的多项式逼近。 当前版本仅考虑单数和双数浮点多项式,其度数最多为16,仅适用于一些先验条件:sin,cos,atan,exp,log,log1px和lg1px。 效率度量标准是:多项式的阶数,非零乘数的数量,非{-1、0、1}乘数的数量,非{-2,-1、0、1、2}的数量乘数,以及常数偏移量等于0、1、2还是其他(3)。 乘数的度量结构反映出乘以零(即不执行任何操作)的速度至少与乘以1的速度一样快,乘数本身至少与乘以2的速度一样快。 但是,乘以3或其他整数似乎是不可利用的:当前x86上的FP乘法器几乎与加法器一样快。 在考虑的输入范围内以最大绝对误差测量精度; 还报告了舍入为2的对数舍入( lb_error ),以在离散存储区中分配准确性。 single/目录报告单浮点近似值,而double/报告双浮点近
