boolean function ( long arg0 ) { return arg0 > 0 & ( arg0 & ( arg0 - 1 ) ) == 0 ; }
returns true if x represents a power of two.this differs from long.bitcount x == 1 , because long.bitcount long.min _ value == 1 , but long #min_value is not a power of two . concode_field_sep long MAX_POWER_OF_SQRT2_UNSIGNED concode_elem_sep long FLOOR_SQRT_MAX_LONG concode_elem_sep int[] biggestBinomials concode_elem_sep byte[] maxLog10ForLeadingZeros concode_elem_sep int[] biggestSimpleBinomials concode_elem_sep long[] factorials concode_field_sep long mean concode_elem_sep int lessThanBranchFree concode_elem_sep long gcd concode_elem_sep long binomial concode_elem_sep int log2 concode_elem_sep long multiplyFraction concode_elem_sep boolean fitsInInt
