Number, Currency & Percentage Fields
This article explains how Number, Currency, and Percentage fields work in the Sintel Apps Designer and how to configure them correctly. When added to a form, they create corresponding numeric columns in the underlying SharePoint list.

1. Number Field
What It Is – A general-purpose numeric field for whole numbers or decimals.
Best Used For:
- Quantities
- Scores
- Counts
- Numeric references
- Measurements
Key Properties:
Decimals – Controls the number of decimal places allowed. Can be set manually or left as Automatic.
Minimum Value – Defines the lowest allowed value.
Maximum Value – Defines the highest allowed value.
Default Value – Set a pre-filled number if required.
Calculated – If enabled, the value can be calculated (used in advanced scenarios).
Placeholder – Text shown before a value is entered.
When to Use:
Use Number when the value:
- Does not represent money
- Is not a percentage
- Needs numeric validation
- May be used in logic or calculations
2. Currency Field
What It Is: A numeric field specifically formatted for monetary values.
Best Used For:
- Budget amounts
- Expense claims
- Project costs
- Financial approvals
Key Properties:
Decimals – Controls decimal precision (typically 2).
Minimum / Maximum Value – Restrict allowed monetary range.
Format – Defines currency display format (e.g. $1,234.56).
Default Value – Pre-populate with a value if required.
Calculated – Can be used in calculated scenarios.
When to Use
- The value represents money
- Formatting consistency is important
- The field may appear in financial reporting
- Workflow approval thresholds depend on amount
3. Percentage Field
What It Is: A numeric field formatted as a percentage.
Best Used For
- Completion rates

Key Properties
Decimals – Controls precision of the percentage value.
Minimum Value – Typically set to 0.
Maximum Value – Commonly set to 100.
Default Value – Pre-fill if necessary
Calculated – Can be enabled for formula-based results.
When to Use
Use Percentage when:
-
The value represents a proportion
-
You need validation within a 0–100 range
-
The value may drive logic conditions
Shared Properties (All Three Types)
All numeric fields also include:
-
Title – Field label
-
Required – Makes the field mandatory
-
Unique – Prevents duplicate values (rarely used)
-
State – Editable, Read-only, or inherited

Theme and Styling – Font, size, colour
These fields can also be used in Logic rules and Workflow conditions.
Number vs Currency vs Percentage

|---|---|
| General numeric input | Number |
| Monetary value | Currency |
| Proportion or rate | Percentage |
Using Numeric Fields in Logic
Numeric fields are commonly used to:
-
Trigger approval levels
-
Validate ranges
-
Show or hide sections
-
Calculate totals
Example:
If Total Cost > 10,000, require Director approval.
Numeric validation improves process control.
Best Practices
-
Test numeric-based workflow conditions thoroughly.
-
Avoid Using Number instead of Currency for financial data
-
Don’t allow unnecessary decimal places
