StringToDecimal - how to avoid to Rounding

[anu123]

I have source field geocode and value as below..
source - Geocode = 40.145000|-84.24860

I need to parse above value into Latitude & Longitude

Latitude = 40.145
Longitude = -84.2486

I am using below transformations

Latitude = StringToDecimal(Field(geocode,"|",1))
Longitude = StringToDecimal(Field(geocode,"|",2))

The outpur I am getting is

Latitude = 40.145
Longitude = -84.249

I tried using using RTYPE option 'floor' on StringToDecimal but values are getting truncated.

Is there a way to convert string to decimal with any kind of rounding..

Specify a larger scale value than 3.

Specify a larger scale value than 3.

Thanks Ray.

I have specified Decimal(31,10). Even though it is getting rounded.
