It is crucial to handle numerical values with precision, especially when dealing with calculations or financial data. One common requirement is to round off a value to one decimal place and ensure that there is always a trailing zero for added precision.
function roundToOneDecimalPlaces(context, fieldName) {
// Access the current record in the context
var currentRecord = context.currentRecord;
// Retrieve the original value from the specified field
var value = currentRecord.getValue({
fieldId: fieldName
});
// Round off to one decimal place
var roundedValue = Math.round(value * 10) / 10;
// Convert the rounded value to a string
var stringValue = roundedValue.toString();
// Add zero at the end if there is no digit after the decimal point
if (stringValue.indexOf(‘.’) === -1) {
stringValue += ‘.0’;
}
// Add zero at the beginning if the value is between 1 and 0
if (roundedValue < 1 && roundedValue > 0) {
stringValue = ‘0’ + stringValue;
}
// Set the modified value back to the current record
currentRecord.setValue({
fieldId: fieldName,
value: stringValue
});
}
