# 2.70 FAQ-784 How can I use comma as decimal mark and use semicolon as function arguments separator in formula and script?

Last Update: 1/8/2019

If you set the separator in Origin menu Preferences: Options: Numeric Format tab, Separators = 1.000,0, Origin will use comma as decimal mark and use a semicolon as function arguments separator in formula for these tools:

For example, you can use formula below to set column values in Set Values dialog:

data(0;2;0,5)

You can turn off this conversion by setting:

SYSTEM.NUMERIC.FORMULASMARTFUNCARGSEP=0;  //default is 1

in Script Window.

If you want to apply the conversion above in Script Window, Command Window, Labtalk Console(in Code Builder) as well, you can set

SYSTEM.NUMERIC.SCRIPTSMARTFUNCARGSEP=1;  //default is 0

in Script Window. For example, you can run the following example in Script Window to set column value:

SYSTEM.NUMERIC.SCRIPTSMARTFUNCARGSEP=1 //set the value to be 1

// use comma as decimal mark
// use semicolon as function arguments separator

col(1)=rmod2(8; 1,5);
