Please give me advice

[a]

I will design account data base but I don't know what data type I will use:

Number Field

Or Currency Field

And What difference between them

Notes:

I will use the field in many calculation

 

[Allen Browne]

For whole numbers, use a Number field of size Long.

For dollars and cents, use Currency. (Also useful for other numbers where
you need 4 decimal places or fewer.)

For other fractional numbes, use a Number field of size Double. (Also useful
for enormous or miniscule numbers.)
