Coercion / python

During an operation with two arguments of the same type, the implicit conversion of one type's instance to another. For example, int(4.28) converts a floating point number to an integer 4.

   in[]    x = int(4.28)             print(x)  out[]    4

But in 4+2.8, each argument is of a different type (one int, one float), and both must be converted to the same type before they can be added, or a TypeError is raised. Without coercion, the programmer would have to normalize all arguments, even those of compatible types, to the same value, e.g., float(4)+4.5 instead of just 4+2.8.

   in[]    sum = (4 + 4.28)             print(sum) out[]    8.28
