# Criteria

Some functions, such as `SUMIF()`, take a **criteria** parameter that other values are compared to. A criteria value can be a literal value, such as `1`, `FALSE`, `"blue"`, etc. A literal value checks for equality (case-insensitive). However, starting a string with a comparison operator enables more complex criteria:

| **Symbol**               | **Description**                                                                              |
| ------------------------ | -------------------------------------------------------------------------------------------- |
| `"=blue"` or `"==blue"`  | Equal comparison (supports [wildcards](https://docs.quadratichq.com/formulas/wildcards))     |
| `"<>blue"` or `"!=blue"` | Not-equal comparison (supports [wildcards](https://docs.quadratichq.com/formulas/wildcards)) |
| `"<blue"`                | Less-than comparison                                                                         |
| `">blue"`                | Greater-than comparison                                                                      |
| `"<=blue"`               | Less-than-or-equal comparison                                                                |
| `">=blue"`               | Greater-than-or-equal comparison                                                             |
