+# decimal
+
+Arbitrary-precision fixed-point decimal numbers in go.
+
+NOTE: can "only" represent numbers with a maximum of 2^31 digits after the decmial point.
+
+## Usage
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/jellolabs/decimal"
+)
+
+func main() {
+	price, err := decimal.NewFromString("136.02")
+    if err != nil {
+        panic(err)
+    }
+
+	quantity := decimal.NewFromFloat(3)
+
+	fee, _ := decimal.NewFromString(".035")
+	taxRate, _ := decimal.NewFromString(".08875")
+
+    subtotal := price.Mul(quantity)
+
+    preTax := subtotal.Mul(fee.Add(decimal.NewFromFloat(1)))
+
+    total := preTax.Mul(taxRate.Add(decimal.NewFromFloat(1)))
+
+	fmt.Println("Subtotal:", subtotal)
+	fmt.Println("Pre-tax:", preTax)
+    fmt.Println("Taxes:", total.Sub(preTax))
+	fmt.Println("Total:", total)
+	fmt.Println("Tax rate:", total.Sub(preTax).Div(preTax))
+}
+```
