Cumulocity Data Types Handling

Question

How does one handle different data types in the Cumulocity IoT Cloud? Things like: Double - Double precision floating-point value in accordance to IEEE754 Float - Single precision floating-point value in accordance to IEEE754 Decimal - Decimal with arbitrary precision Long - Signed 64bit integer value Int - Signed 32bit integer value Short - Signed 16bit integer value Byte - Signed 8bit integer value

Answer 1

Cumulocity attempts to preserve the data it is presented with, up to what it can fit in 64-bits. If it receive an integer which can fit in 32 bits C8Y will store it that way, similarly if it's an integer which is too big for 32 bits but fits in 64 bits then it is stored as a 64-bit integer. Otherwise an IEEE 754 64-bit binary float is used. Some reference to the docs: https://cumulocity.com/guides/reference/measurements/#measurement v10.6.0
