Question

what's the purpose/point of the REAL() Datatype in mysql? You have float,double and decimal which i understand but where does the "real" datatype come into it? Any ideas?

Thank you in advance ;-)

is real the same as float or double?

Answer 1

MySQL treats REAL as a synonym for DOUBLE, unless the REAL_AS_FLOAT SQL mode is enabled.
