核心数学函数的Java BigDecimal实现

A Java Math.BigDecimal Implementation of Core Mathematical Functions

Richard J. Mathar

摘要:

数学函数log(x)、exp(x)、root[n]x、sin(x)、cos(x)、tan(x)、arcsin(x)、arctan(x)、x^y、sinh(x)、cosh(x)、tanh(x)和Gamma(x)已经在本地Java库中的实域中针对参数x在浮点数的多精度BigDecimal表示之上实现。这支持需要标准版库的两倍以上精度的科学应用。完整的信源编码在LGPL v3.0下提供。

英文摘要:

The mathematical functions log(x), exp(x), root[n]x, sin(x), cos(x), tan(x), arcsin(x), arctan(x), x^y, sinh(x), cosh(x), tanh(x) and Gamma(x) have been implemented for arguments x in the real domain in a native Java library on top of the multi-precision BigDecimal representation of floating point numbers. This supports scientific applications where more than the double precision accuracy of the library of the Standard Edition is desired. The full source code is made available under the LGPL v3.0.
