Dear statalist,

I have a problem with data precision as follows:

for example: glycated hemoglobin is 6.1 (%) visible in data editor,
but it turns out 6.0999999 when clicked on, so are other numbers (5.6
becomes 5.5999999), etc. This affects results of creating dummy
variables with pre-defined cut-points of values. How about the
solution?

Thank you for your advice
