class long(x=0) → long

long(x, base=10) -> long

Convert a number or string to a long integer, or return 0L if no arguments are given. If x is floating point, the conversion truncates towards zero.

If x is not a number or if base is given, then x must be a string or Unicode object representing an integer literal in the given base. The literal can be preceded by ‘+’ or ‘-‘ and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal. >>> int(‘0b100’, base=0) 4L


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


bit_length() Number of bits necessary to represent self in binary.
conjugate Returns self, the complex conjugate of any long.


denominator the denominator of a rational number in lowest terms
imag the imaginary part of a complex number
numerator the numerator of a rational number in lowest terms
real the real part of a complex number
