Basic math operations using dataweave
Download as PPTX, PDF1 like5,745 views
This document demonstrates how to perform basic math operations like addition, subtraction, multiplication, division, finding maximum and minimum values, rounding, and square root functions using DataWeave. It provides code examples for each operation, showing how to transform and output the results in JSON or XML format.
![Max
• (':array')/(':object') ⇒ ':number'
• Returns the highest number in an array or object.
• %dw 1.0
• %output application/json
• ---
• {
• a: max [1..1000],
• b: max [1, 2, 3],
• d: max [1.5, 2.5, 3.5]
• }](https://image.slidesharecdn.com/basicmathoperationsusingdataweave-161228041156/85/Basic-math-operations-using-dataweave-9-320.jpg)
![Min
• %dw 1.0
• %output application/json
• ---
• {
• a: min [1..1000],
• b: min [1, 2, 3],
• d: min [1.5, 2.5, 3.5]

Basic math operations using dataweave
- 1. Basic Math Operations using Dataweave
- 2. Transform • Sum • %dw 1.0 %output application/xml --- plus : 2 + 2.5
- 3. output
- 4. Minus • %dw 1.0 • %output application/xml • --- • minus : 2.5 - 2
- 5. Multiply • %dw 1.0 • %output application/xml • --- • multiply : 2.5 * 2
- 7. Division • %dw 1.0 • %output application/xml • --- • division : 10 / 2
- 9. Max • (':array')/(':object') ⇒ ':number' • Returns the highest number in an array or object. • %dw 1.0 • %output application/json • --- • { • a: max [1..1000], • b: max [1, 2, 3], • d: max [1.5, 2.5, 3.5] • }
- 12. Min • %dw 1.0 • %output application/json • --- • { • a: min [1..1000], • b: min [1, 2, 3], • d: min [1.5, 2.5, 3.5] • }
- 14. Round • (':number') ⇒ ':number' Rounds the value of a number to the nearest integer • %dw 1.0 %output application/json • --- • { • a: round 1.2, • b: round 4.6, • c: round 3.5 • }
- 16. Sqrt • %dw 1.0 %output application/json • --- • { • a: sqrt 4, • b: sqrt 25, • c: sqrt 100 • }
