FAQ023 = What is the maximum size of a number?
16-bit signed integer, Max = (2^15)-1 = 32,767
32-bit signed integer, Max = (2^31)-1 = 2,147,483,647
single-precision 32-bit floating-point
Seven place accuracy, Max = 3.402823E+38
double-precision 64-bit floating-point
Sixteen place accuracy, Max = 1.797693134862315D+308
Note: "K" is treated the same as "K!", in other words, the default selection is SINGLE. Of course if the user enters, for example
DIM K AS INTEGER
then "K" will be treated as "K%"
What happens when you reach end-of-range:
E%=E%+1: 'This is OK
E%=E%+1: 'This causes OVERFLOW error
K=3.402822E+38: 'Note that "K" is the same as "K!"
K=K+0.000001E+38: 'This is OK
K=K+0.000001E+38: 'This causes OVERFLOW error
But look at this:
K!=K!+0.000001E+38: 'This is OK as before
K!=K!+10000000000000: 'This does nothing
This is because the number 10000000000000 is insignificantly small compared to 1E+38
Anything less than 0.000001E+38 will do nothing.
But 0.000001E+38 will cause an overflow.
(0.000001E+38 is usually written as 1E32)
