Implicit type conversions
"
Integral og floating-point types can be mixed freely in assignments and expressions
"
The C++ Programming Language
: Page 833
"
Fundamental types can be converted to each other in a bewildering number of ways
"
Promotions
A kind of
normalization
to certain integer types and floating point types before arithmetic operations
Usual Arithmetic conversions
Convert arguments of binary operators to a common type
Conversion to boolean
From pointers, integers, and floating point types
Non-zero value transformed to
true
and zero to
false
Conversion between integer types
Unsigned: Cutting off bits
Signed: Implementation dependent
Conversion between floating point and integer types
May cause loss of information, or may be undefined (in case of range problems)
