mean value in QAMR


Hi Experts,

When I do result recording to a quan. char. A, the decimal place is 1. I input 27.45 as result, and 27.5 shows as Mean value of result for char. A, that is correct. But when I check the table QAMR, the field MITTELWERT as Arithmetic Mean of Valid Measured Values shows 2.7449999999999999E01. So could anyone can explain to me why this situation happened? Why doesn't the system store this value as 2.7450000000000000E01 in the table?

Many thanks in advance.
