ParseJson does not handle negative numbers

Has anyone encountered an issue where the parsejson method when it parses out a Json integer that is a negative value it forces it as a positive value? so for example i have this json string

{test: -1} but when i run the parse json on it the value of test = 1 instead of -1?

This seems to show that it works. Can you post code where it doesn’t work?


BrightScript Debugger> s="{"+chr(34)+"test"+chr(34)+": -1}"
BrightScript Debugger> ?s
{"test": -1}
BrightScript Debugger> j= ParseJSON(s)
BrightScript Debugger> ?j
test: -1

jsonString = “{” + Chr(34) + “test” + Chr(34) + “:” + Stri(-1).trim() + “}”
print jsonString

print Stri(ParseJson(jsonString).test)

the first print out works and displays the right json with the negative value but after I parse and get the attribute test from the json array it returns as 1

This works for me. What firmware version are you running?

BrightScript Debugger> jsonString = "{" + Chr(34) + "test" + Chr(34) + ":" + Stri(-1).trim() + "}"
BrightScript Debugger> ?jsonString
{"test":-1}
BrightScript Debugger>  print Stri(ParseJson(jsonString).test)
-1
