How set null value in fields type Double?

[Alexander]

Hi Team!
Help me please for my problem :(

We need that fields calculated  ("stp","def_prod") and write sum in fields ("adm","total").

We have this script in behaviour plugin:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.fields.CustomField;

//Take fields by name

def stp = getFieldByName("cf1Name");
def adm = getFieldByName("cf2Name");
def total = getFieldByName("cf3Name");
def def_prod = getFieldByName("cf4Name");

//Take the value from the field and assign the type Double

def value_stp = stp.getValue() as Double
def value_def = def_prod.getValue() as Double


if (value_stp != null & value_def != null){
def sum_adm = (value_stp + value_def) * 0.15
adm.setFormValue(sum_adm)
total.setFormValue(value_stp + sum_adm)

}
else {
//Set null if value_stp\value_def = null 

adm.setFormValue(null)  
total.setFormValue(null)
}

Values are calculate. But after delete value fields ("stp", "def_prod") "adm" and "total" is not set null.
How cleaning Double field's value in Behaviour?

Thanks!

I found error in my script.
When i cleared my custom fields they have type "String".
When i write value they have type "Double".
Because of this condition "if" not work and value in customfield not cleared.

Below correcte script:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.fields.CustomField;

def stp = getFieldByName("cfName");
def adm = getFieldByName("cf2Name");
def total = getFieldByName("cf3Name");
def def_prod = getFieldByName("cf4Name");


if (stp.getValue() != "" && def_prod.getValue() != ""){
def sum_adm = ((stp.getValue() as Double) + (def_prod.getValue() as Double)) * 0.15

adm.setFormValue(sum_adm)
total.setFormValue((stp.getValue() as Double) + sum_adm)

}
else {
adm.setFormValue(null)
total.setFormValue(null)
}
