How can a signed 64 bits QUAD integer in PB be converted to a unsigned 64

bit integer?

Thanks!

bit integer?

EXT variables:

f80## = CEXT(i64&&)

...but note that due to how QUADs are implemented, and the limitations of

floating-point types, very large values lose precision. (Read the help file's

QUAD and EXT entries.) If that's not acceptable, you'll need to roll your own

data type. Google for something like "implement unsigned 64-bit integer

basic".

If you absolutely *must* have an unsigned 64-bit integer, and don't want to

roll your own, you'll need to use a different language. (For example,

FreeBASIC has ULONGINT, and QB64 (apparently) has _UNSIGNED _INTEGER64.)

Just so happens that I had been researching the EXT data type for

the same purpose so I had the links bookmarked already.
