From source file:org.talend.dataprep.transformation.actions.math.TemperaturesConverter.java

@Override
protected String calculateResult(String columnValue, ActionContext context) {
    TemperatureUnit fromTemperatureUnit = TemperatureUnit
            .valueOf(context.getParameters().get(FROM_UNIT_PARAMETER));
    TemperatureUnit toTemperatureUnit = TemperatureUnit.valueOf(context.getParameters().get(TO_UNIT_PARAMETER));
    String precisionParameter = context.getParameters().get(TARGET_PRECISION);

    BigDecimal value = BigDecimalParser.toBigDecimal(columnValue);
    TemperatureImpl fromTemp = new TemperatureImpl(value, fromTemperatureUnit.asJavaUnit());
    TemperatureImpl temperature = fromTemp.convertTo(toTemperatureUnit.asJavaUnit());

    // Precision is used as scale, for precision as significant digits, see history
    Integer targetScale = NumberUtils.toInt(precisionParameter, value.scale());
