Ho everyone
I have a column in a table defined as float
mynumber float(20,2)
if we say mynumber column in a row is 1000000 , when I run this SQL :
UPDATE Table SET mynumber=mynumber-100.15
the mynumber column will be 999900 not 999899.85
what is the problem ?
Ho Ho Ho,
Float only uses 4 bytes and does not have much precision so you'll get
rounding. Try DOUBLE instead.
