I do believe it's important to avoid unnecessary casts as much as possible and leave it up to the user making cast explicit than implicit else the behavior gets quite unpredictable.Hi,IMHO, the more meaningful cases of the RFC are missing : round(float, precision: >= 0): int|float // only cast to float for int overflow ceil(float): int|float // only cast to float for int overflow floor(float): int|float // only cast to float for int overflowCalling ceil or floor on integer is meaningless, because it will return the same value.The RFC should be "Prefer int as return value when possible".
Implicitly casting to float only happens on int underflow/overflow. Implicitly casting to int will never happen.
As you say "Calling ceil or floor on integer is meaningless, because it will return the same value." this is already noted in the RFC and the functions will be a no-op in this case.
