>>Hi All,
>>
>>In all my years of using VFP I cannot remember ever using a Double type field in a table. Now I need to store numeric values which exceed 10 digits before the decimal point and up to 4 digits after the decimal point giving me a numeric field of 15,4. However, I notice that a double field type takes up 8 bytes which would be less than a numeric field catering for 15,4. Are there any obvious problems or issues to be aware of if I convert to using doubles as a field type, any things to watch or check for?

I use it only seldom, mostly for very large counters - mostly =+ type of counting.
But if you need 19 digits of precision, would you trust vfp's numeric esp. if vfp help is quite open about precision ?
Perhaps the safest way would be to use C(20) and work from there if no calculation is needed.
