LAMBDA
The LAMBDA function allows you to define a subformula that accepts up to 253 parameters as input.
LAMBDA(parameter, parameter…, calculation)
parameter: An input that defines the value you are passing through the formula.
parameter…: Optionally include one or more additional parameters.
calculation: The formula you want the function to execute and return. This is required and must be the last argument.
Notes
LAMBDA allows you to define values that are represented as formula tokens. Once defined, they can appear in type-ahead and used elsewhere in the function.
If you only input a LAMBDA function into a cell, it returns an error. In order to test the LAMBDA function and return a value, use the LAMBDA.APPLY function. See the examples below.
When an Excel spreadsheet containing LAMBDA functions is imported into Numbers, each formula referencing a LAMBDA function receives a local copy of the definition.
Use the LAMBDA.APPLY function when testing a LAMBDA function imported from Excel.
LAMBDA functions can be used and referenced only in the cell in which they are defined.
LAMBDA functions cannot be nested.
Examples |
|---|
Suppose you want to test a LAMBDA function that converts a temperature from Fahrenheit to Celsius, and you have a temperature value in cell A1. =LAMBDA.APPLY(A1, LAMBDA(temp, (temp-32)*5/9)). |
