解析数学函数PL/SQL [英] Resolve Math Functions PL/SQL

问题描述

我需要在pl/sql中解析数​​学方程式/函数.
oracle pl/sql提供了哪些数学运算/函数可以帮助我解析这样的数学函数:

I need to resolve a math equation/function in pl/sql.
What kind of math operations/functions are available in oracle pl/sql that could help me resolve a math function like this :

(3.5/(1+x))+(3.5/(1+x)^2)+(3.5/(1+x)^3)+(3.5/(1+x)^4)+(100/(1+x)^4)=101.55

我想要一个函数来解析此语句并找出x的值.

I want a function to resolve this statement and find out the value of x.

有帮助吗?谢谢.

推荐答案

可惜Oracle数据库不是数学工具.它具有许多算术和统计函数但它没有能够解释方程式的内置功能.对不起.

Alas the Oracle database is not a mathematical tool. It has lots of arithmetical and statistical functions but it doesn't have built-in functionality capable of interpreting equations. Sorry.

Marc巧合(又名 Odie_63 )最近已发布他用PL/SQL编写的反向波兰符号表示计算器.它并不能完全满足您的要求，但是我提供了一个链接，以供将来可能偶然发现此线程的所有寻求者使用. 了解更多信息.

By sheer coincidence Marc (AKA Odie_63) has recently published a Reverse Polish Notation calculator which he has written in PL/SQL. It doesn't do precisely what you want but I'm including a link for the benefit of any seekers who may stumble upon this thread in the future. Find out more.
