Method Details [hide private]

__init__(self, integer, signed, nptype, _gltype=None, charcode=None)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

str(x)

Overrides: object.__str__
(inherited documentation)

__repr__(self)
(Representation operator)

source code 

repr(x)

Overrides: object.__repr__
(inherited documentation)

coerced(self, force_integer=False, force_unsigned=False, force_float=False, force_gl=True)

source code 

Find a datatype with the specified properties.

The returned datatype will match `self` as closely as possible. If `force_integer` is `True`, it will be an integer datatype. If `force_unsigned` is `True`, it will be an unsigned datatype. If `force_float` is `True`, it will be a floating point datatype. If `force_gl` is `True`, it will have an OpenGL equivalent.

If conversion of `self` to the resulting datatype would likely result in a severe loss of precision or overflows, an error may be raised.
