HI
I'm getting an issue where an api response is returning a float for a user id, i.e
{"user_id" : 20715915.0}
I want to convert this to an INT by applying:
INT(20715915.0)
but this returns 20715916
instead of 20715915
Can anyone help me here?
though "INT" should return what you are expecting try "CINT"

Thanks for the quick response but CINT also returns the same, I've tried that already.
Brightscript Debugger> p CINT(20715915.0)
20715916
This is a limitation of the 32-bit IEEE floating point representation used by the BrightScript Float type, and the global functions Int and CInt which take a parameter of that type.
In your own calculations you may be able to use the BrightScript Double (and LongInteger) types if you need greater precision.
Unfortunately it is a known issue that for backward compatibility reasons the ParseJSON function will emit a Float value rather than Double for values that fit in the Float range, which may result in the IEEE precision/rounding issues with conversions such as you have found.
