Return to CPP double keyword
Creating an exhaustive list of 30 programming languages that support the reserved word `double` (used for declaring double-precision floating-point numbers) is challenging due to the specificity of the request. However, I can list several prominent programming languages that use `double` or an equivalent concept, along with their official documentation and Wikipedia links where applicable. It's worth noting that not all programming languages might use the exact keyword `double` to denote a double-precision floating-point number, but the concept is widely supported across programming languages for numerical computations requiring high precision.

This list includes programming languages that support double-precision floating-point numbers directly through the `double` keyword or an equivalent concept, demonstrating the importance of this data type in numerical computing across a wide range of programming environments. The exact implementation details and precision can vary, so consulting the official documentation is recommended for specific applications and understanding the nuances of each language's number system.
