2,850 PointsI seem to get an error when running one of the go challenges
Ok so where's the question. I believe my code is working but I get an error.
challenge:
In the sales package, define an exported CalculateTax function. CalculateTax should accept a float64 parameter representing a sales total, and a second float64 parameter representing a tax rate. The function should multiply the sales total by the tax rate, and return the result as a float64 value. So, for example, sales.CalculateTax(100.0, 0.08) should return approximately 8.0. (Very small floating-point math errors are OK.)
Error: Bummer! # command-line-arguments ./report.go:9: multiple-value sales.CalculateTax() in single-value context
My code description:
The error appears on "func CalculateTax(salesTotal, taxRate float64) (float64, error) {"
package sales
import ( "fmt" )
func CalculateTax(salesTotal, taxRate float64) (float64, error) { result := salesTotal * taxRate // Check the value if result <= 0 { return result, fmt.Errorf("Please check your sales total %f and tax rate %f", salesTotal, taxRate) } return result, nil }
Now I believe the treehouse code check won't accept parameters since the error string calls sales.CalculateTax(). Not a 100% sure but wanted to check with you all.
package sales
import (
"fmt"
)
func CalculateTax(salesTotal, taxRate float64) (float64, error) {
result := salesTotal * taxRate
// Check the value
if result <= 0 {
return result, fmt.Errorf("Please check your sales total %f and tax rate %f", salesTotal, taxRate)
}
return result, nil
}

231,236 PointsYou got a bit too fancy. The challenge was looking specifically for the function to take two arguments and return one. Adding in the error return was confusing the check mechanism.
