For some databases, you get better precision, if you cast/convert to float data type in the SQL statement.

Examples

Reads floating point value from field TotalSales into variable:

$x = MBS("SQL.GetFieldAsFloat"; $command; "TotalSales")

Reads floating point value from 2nd field into variable:

$x = MBS("SQL.GetFieldAsFloat"; $command; 2)

Read null value as empty, otherwise get floating number:

If(
      MBS("SQL.GetFieldIsNull"; $command; "FieldName");
      "";
      MBS("SQL.GetFieldAsFloat"; $command; "FieldName"))
