Hmmm ... when reading the description of Single it sounds w-a-y different!
Up to seven decimal places and a maximum value of 3.402823 ^ 38

I get it ... I had already decided to go with Double .. but I wanted to
understand the why of the behavior.

So, bottom line is even though the maximum value is significantly higher, if
I want something grater than a 7 digit number, stay away friom Single.

Thanks for the enlightenment!

Single is a floating point number, with only around 7 significant digits.

Use Double, or Decimal.

I have a field with NUMBER datatype, SINGLE field size, Fixed format and 0
Decimals. When I enter the value 100317090407 the number rewrites itself
as
100317100000. When I enter 100317090417 again I get 100317100000. When I
enter 100317090499 once again I get 1003617100000.

My number is clearly under then max for a Single 3.402823E38, so what is
going on?

If I set my field size to DOUBLE, I do not encounter the same problem, but
I
don't get it. Why do my numbers seem to have a mind of their own with the
SINGLE field size?
