Hi,
I am trying to convert this decimal number to binary: 297237575406453000
I am using bin2dec(297237575406453000) and I get 10000100000000000000000000000000000000000000000000100000000
However, the answer seems to be wrong, if I do it in the windows calculator the result is ‭010000100000000000000000000000000000000000000000000100001000‬ and I verified in python and the conversion is the same as windows calculator
Is it an error in the function? or am I doing something wrong?

You are not doing wrong - just read the documentation:
"...If the input argument D has a value greater than the value returned by flintmax, then dec2bin might not return an exact representation."
>> flintmax < 297237575406453000
