示例1: Decode
//Decode is the inverse operation of Encode.
//Decode returns latitude, longitude, and whether or not they are both represented precisely as float64 types.
func Decode(bucket int64) (float64, float64, bool) {
var latitudeUnshifted, longitudeUnshifted decimal.Decimal
var latitude, longitude float64
var err error
var exact bool
bucketString := strconv.FormatInt(bucket, 10)
for len(bucketString) < 18 {
bucketString = "0" + bucketString
}
latString, lonString := unzip(bucketString)
latString = latString[0:3] + "." + latString[3:]
lonString = lonString[0:3] + "." + lonString[3:]
latitudeUnshifted, err = decimal.NewFromString(latString)
longitudeUnshifted, err = decimal.NewFromString(lonString)
if err != nil {
fmt.Errorf("Error creating decimal from string")
}
latitudeUnshifted = latitudeUnshifted.Sub(decimal.NewFromFloat(90.0))
longitudeUnshifted = longitudeUnshifted.Sub(decimal.NewFromFloat(180.0))
latitude, exact = latitudeUnshifted.Float64()
longitude, exact = longitudeUnshifted.Float64()
return latitude, longitude, exact
}示例2: Calculate
func (sc *salaryCalculator) Calculate(grossSalary, dependentsQty decimal.Decimal) Salary {
inss := sc.inss.Calculate(grossSalary)
dependents := sc.depedents.Calculate(dependentsQty)
irrfBase := grossSalary.Sub(inss).Sub(dependents)
irrf := sc.irrf.Calculate(irrfBase)
netSalary := grossSalary.Sub(inss).Sub(irrf)
return Salary{
GrossSalary: grossSalary,
INSS: inss,
Dependents: dependents,
IRRF: irrf,
NetSalary: netSalary,
}
}示例3: newton
func newton(z, x decimal.Decimal) decimal.Decimal {
return z.Sub(z.Mul(z).Sub(x).Div(Const2.Mul(z)))
}
