PPP Deflate压缩协议（PPP Deflate Protocol） 摘要 点到点协议（PPP）[1]提供了一种在点到点链路上传输多协议数据报的标准方法。压缩控制协议（CCP）[2]提供了一种在PPP封装链路上协商和使用压缩协议的方法。本文档描述了如何使用PPP Deflate压缩协议压缩PPP封装报文。 -PPP Deflate compression protocol (PPP Deflate Protocol) Abstract point-to-point protocol (PPP) [1] provides a point-to-point link, the multi-protocol data transmission of standard methods. Compression Control Protocol (CCP) [2] provides a link in the PPP Packaging consultations on the agreement and the use of compression method. This document describes how to use the PPP Deflate compression compression PPP agreement Packaging paper reported.

除了支持一般的小数运算，还支持常见的函数运算。 几个包中的MathFP是针对不同需要而提供的不同版本，开发J2ME只要使用net.jscience.math.MathFP就可以。-addition to general support for the fractional arithmetic, but also the common computing functions. Several packets of MathFP is different needs of the different versions, as long as the use of J2ME development net.jscience.math.MathFP can.
