otp.long#

class long(value, *args, **kwargs)#

OneTick data type representing signed long integer.

The size of the type is not specified and may vary across different systems. Most commonly it’s a 8-byte type with allowed values from -2**63 to 2**63 - 1.

Note that the value is checked to be valid in constructor, but no overflow checking is done when arithmetic operations are performed.

Examples

>>> t = otp.Tick(A=otp.long(1))
>>> t['B'] = otp.long(1) + 1
>>> t.schema
{'A': <class 'onetick.py.types.long'>, 'B': <class 'onetick.py.types.long'>}
