Higher Math(高等数学)

The functions you’ve seen so far are the beginning of the built-in mathematical functions. Lisp also supports logarithms: LOG; exponentiation: EXP and EXPT; the basic trigonometric functions: SIN, COS, and TAN; their inverses: ASIN, ACOS, and ATAN; hyperbolic functions: SINH, COSH, and TANH; and their inverses: ASINH, ACOSH, and ATANH. It also provides functions to get at the individual bits of an integer and to extract the parts of a ratio or a complex number. For a complete list, see any Common Lisp reference.

目前为止,你所看到的函数只是初级的内置数学函数。Lisp 也支持对数函数:LOG,指数函数:EXPEXPT,基本三角函数:SINCOSTAN 及其它们的逆:ASINACOSATAN,双曲函数:SINHCOSHTANH 以及它们的逆:ASINHACOSHATANH。它还提供了函数用来获取一个整数中单独的位以及取出一个比值或一个复数中的部分。完整的函数列表参见任何 Common Lisp 参考。
