If you want to covert it to numeric type, you can use the pipeline parameter with [int function](control-flow-expression-language-functions.md#int) or [float function](control-flow-expression-language-functions.md#float). For example, `int(activity('lookup').output.firstRow.VALUE)`, `float(activity('lookup').output.firstRow.VALUE)`| BigDecimal is not supported in Lookup activity.  |

For example: `formatDateTime(activity('lookup').output.firstRow.DATETIMETYPE)`, `concat(substring(activity('lookup').output.firstRow.DATETIMETYPE, 0, 19), 'Z')`|
