# if

if() function is the Standard function available in 200OK.

**Description** : The if function evaluates a logical test and returns one value if the test is true, and another if it is false.

**Syntax** : fx\_if(logical\_test, value\_if\_true, value\_if\_false)

**Example** : fx\_if(2, 3, <) returns 2 as the response, and fx\_if(2, 3, >) returns 3 as the response.

Here we go with simple scenario using the above function.

**Scenario** : In a pricing strategy application, a retailer adjusts product prices based on competitor prices. They utilize a function to determine the final price for each product based on competitor pricing. If the competitor price is lower, the retailer matches it; otherwise, they set their own price.
