Macro to define constants in GuardedF64 that mirror the constants in f64.

This macro allows you to define constants with a specific type and documentation. It simplifies the process of creating constants that are directly related to the f64 type, ensuring that they are accessible through the GuardedF64 type.

Arguments

• $name: The name of the constant to define.
• $t: The type of the constant (e.g., f64, u32, etc.).
• $value: The value of the constant, which can be a direct reference to an f64 constant or a specific value.
• $doc: A documentation string that describes the constant and its purpose.
