...float
var m = 1.0m; // decimal
var i = 1; // int
var ui = 1U; // uint
var ul = 1UL; // ulong
var l = 1L; // long
I think that's all... there are no literal specifiers for short/ushort/byte/sbyte

Convert base-2 binary number string to int
...g import BitArray
>>> b = BitArray(bin='11111111')

255
Note that the unsigned integer is different from the signed integer:
>>> b.int
-1
