I have a var defined as double - I am using the round() function to set the resulting var to 1 dec place eg :

TempCalc = round( 0.15 , 1 )

Std VB setting is to round up to 0.2 - but is there a setting I can use to round down in this instance - ie the result I want is 0.1

If the value is 0.16 - then yes, I do want it to rounded up to 0.2
