== Why is this an issue?
|
|
|
|
The size of integer that is required when a pointer is converted to an integer is implementation-defined. Casting between a pointer and an integer type should be avoided where possible, but may be unavoidable when addressing memory mapped registers or other hardware specific features.
|
|
|
|
|
|
Note that {cpp} does not permit a pointer to be converted to any floating type.
