This is a library to convert words (three hundred-thousand) to numbers (300,000) in Go
Go get the package:
go get github.com/donna-legal/word2number
and add it as an import:
import "github.com/donna-legal/word2number"package main
import (
"fmt"
"github.com/donna-legal/word2number"
)
func main() {
converter, err := word2number.NewConverter("en")
if err != nil {
panic(err)
}
var f float64
f = converter.Words2Number("two-thousand seventy-five")
fmt.Println(f) // should return 2075
f = converter.Words2Number("one-million two hundred thousand")
fmt.Println(f) // should return 1200000
}Look in the test cases what works and what doesn't. Most things to the left of the decimal point should work.
Needs improvement:
- Decimal numbers. The simpler cases work just fine (eg. one point three hundredths = 1.03), but there are quite a few failing test cases
- Things like One point two billion doesn't check out at the moment either.
Extensions:
- More languages. It would be somewhat easy to extend with other languages that are constructed the same way, like Swedish or Spanish.
- Misspellings. One could extend the resources with common misspellings.
- Concatenations. Some people might write seventyfive instead of seventy-five. This is definitely necessary for Spanish and Swedish.
