Dynamics 365 F&O supports six decimal points. So just extend decimal point field of extended data type doesn't enough:
We need to do a few tricks more:
In first we create a new field for save decimal point and be sure this method below to run after every write (We can call from update/insert methods).
public void updateInterestRateDecimals()
{
this.InterestRateDecimal = (this.InterestRate - real2int(this.InterestRate) ) *
100000000;
}
Than we modify postLoad like this:
public void postLoad()
{
super();
if (this.InterestRateDecimal != 0)
{
this.InterestRate = real2int(this.InterestRate) +
this.InterestRateDecimal / 100000000;
}
}
Result:
