# EVIDENCE-OF: R-65079-31758 Application of a CAST expression is
# different to application of a column affinity, as with a CAST
# expression the storage class conversion is forced even if it is lossy
# and irrreversible.
# EVIDENCE-OF: R-20854-17109 A CAST conversion is similar to the
# conversion that takes place when a column affinity is applied to a
# value except that with the CAST operator the conversion always takes
# place even if the conversion lossy and irreversible, whereas column
# affinity only changes the data type of a value if the change is
# lossless and reversible.
