Learn how to create numerical fields for storing quantities, percentages, currency, and more.

This script demonstrates how to create & work with the following numerical fields in NocoDB:
`Number`, `Currency`, `Decimal`, `Percent`

For detailed descriptions of each field type and associated configuration options, refer to the [NocoDB meta API documentation](https://nocodb.com/apis/v3/meta#tag/Fields).

```javascript
// NocoDB Script: Create Numerical Fields

const tableName = 'Numeric Fields Demo';
let table = base.getTable(tableName);

if (!table) {
  table = await base.createTableAsync(tableName, []);
  output.text(`✅ Created table: "${tableName}"`);
}

async function createField(name, config) {
  if (!table.getField(name)) {
    await table.createFieldAsync({ name, ...config });
    output.text(`✅ Created: ${name}`);
  }
}

await createField('Amount', { type: "Number" });
await createField('Budget', { type: "Currency" });
await createField('Conversion Rate', { type: "Decimal" });
await createField('Progress %', { type: "Percent" });

output.table(table.fields.map(f => ({ 'Field Name': f.name, 'Type': f.type })));
output.text(`ℹ️ Total fields created: ${table.fields.length}`);
```
