REDUCE Function

Description

Apply a Lambda function to each value and return the total value in the accumulator.

NOTE

• The function will return a #VALUE! when you providing an invalid Lambda function. (Common error)
• The initial_value can be omitted, zero, an empty string, or any array..
  If omitted, the value is set to the first element from souce array.

Syntax

Copied!=REDUCE([initial_value], array, LAMBDA(accumulator, source, body))
=REDUCE([initial_value], array, LAMBDA(accumulator, source, body))

EXAMPLE

Copied!//𝘶𝘴𝘦 𝘸𝘪𝘵𝘩 𝘯𝘢𝘵𝘪𝘷𝘦 𝘭𝘢𝘮𝘣𝘥𝘢 𝘰𝘳 𝘯𝘢𝘮𝘦𝘥 𝘭𝘢𝘮𝘣𝘥𝘢 𝘧𝘶𝘯𝘤𝘵𝘪𝘰𝘯
=REDUCE(2, A1:A5, SUM)

//𝘤𝘶𝘮𝘶𝘭𝘢𝘵𝘪𝘷𝘦 𝘴𝘶𝘮 𝘢𝘤𝘤𝘰𝘳𝘥𝘪𝘯𝘨 𝘵𝘰 𝘵𝘩𝘦 𝘦𝘹𝘱𝘳𝘦𝘴𝘴𝘪𝘰𝘯 𝘢+2*𝘣
------------------------
1
1  + 2 * 2 = 5
5  + 2 * 3 = 11
11 + 2 * 4 = 19
19 + 2 * 5 = 29
------------------------
=REDUCE(, SEQUENCE(5), LAMBDA(a, b, a+2*b))
