工具类
func ScientificNotationTransform(numStr string) string {
decimalNum, err := decimal.NewFromString(numStr)
decimalNum = decimalNum.Abs()
if err != nil {
logrus.Errorf("decimal.NewFromString error, numStr:%s, err:%v", numStr, err)
return numStr
}
return decimalNum.String()
}
测试
func TestScientificNotationTransform(t *testing.T) {
var str = "7.814E-7"
s := ScientificNotationTransform(str)
assert.Equal(t, s, "0.0000007814")
str = "-12E-7"
rs := ScientificNotationTransform(str)
assert.Equal(t, rs, "0.0000012")
}
