constrain-system by SICP

overview

implement basic mathematics:

• addition
• subtraction
• multiplication
• division
• square
• sqrt

and multivariate equation

How-to-Use

Use functional expression to represent

9C = 5(F-32)

like this:

C, F := Variable("c"), Variable("f")
Multiplication(
    Params(Constant(9), C),   // left
    Params(Constant(5),Addition(Params(Intermediate()), Params(F, Constant(-32))).GetIntermediate())) // right
)

tips:

expr.GetVariable("a") // can't get variable in superior expr when target variable in inferior expr,
but can predefined the variable and then inject into expr
