# equation-solver
[](https://goreportcard.com/report/github.com/Gabri432/equation-solver)
[](https://pkg.go.dev/github.com/Gabri432/equation-solver)
Un programma che risolverà una qualunque equazione lineare, quadratica e cubica.
## Come usare la libreria
- Scarica il package 'equationsolver':
```
go get -u github.com/Gabri432/equation-solver
```
- Esempio di utilizzo
```go
package main
import (
"fmt"
eq "github.com/Gabri432/equation-solver"
)
func main() {
solution := eq.EvaluateEquation("x^3-4x=5x^2-1")
fmt.Println("real solutions: ", solution.RealSolutions, "\ncomplex solutions:", solution.ComplexSolutions)
myPolynom := eq.Polynom{A: 1, B: 5, C: -4, D: 1}
fmt.Println(myPolynom.SolveEquation())
}
```
=== Output ===
real solutions: [-0.8752..., 0.2013..., 5.6739...]
complex solutions: []
{[0.38196... 2.61803...] [] }
## Funzioni
```go
EvaluateEquations(equation string) EquationSolution
```
- Prende l'equazione in forma di stringa e ritorna il risultato di tipo EquationSolution
```go
ValidateEquation(equation string) string
```
- Controlla se l'equazione inserita dall'utente è valida.
## Tipi
### Polynom
```go
// Crea un polinomio nella forma: ax^3+bx^2+cx+d
type Polynom struct {
a float64
b float64
c float64
d float64
}
```
### EquationSolution
```go
type EquationSolution struct {
realSolutions []float64 // insieme di soluzioni reali
complexSolutions []complex128 // insieme di soluzioni complesse
errorDescription string // messaggio d'errore
```
