Hi,

Do you mean the temperature factor in an ATOM line,
columns 61 to 66?

http://www.wwpdb.org/documentation/format32/sect9.html

According to the spec that should be formatted as "Real (6.2)",
which I think means at most six characters and fixed two decimal
places, i.e. something like XXX.XX, which means you can't store
0.344 here, according to the spec you can only store 0.34.
