Name Type Description i Int The integer whose bits are being inspected. bit_index Int The index of the bit to check (1-indexed). .TE .SH RETURN Whether or not the given bit index is set to 1 in the binary representation of the integer. .SH NOTES For fixed-size integers, the bit index must be between 1 and the number of bits in that integer (i.e. 1-64 for `Int64`). For `Int`, the bit index must be between 1 and `Int64.max`. Values outside this range will produce a runtime error. .SH EXAMPLES .EX assert 6.get_bit(1) == no assert 6.get_bit(2) == yes assert 6.get_bit(3) == yes assert 6.get_bit(4) == no .EE .SH SEE ALSO .BR Tomo-Int (3)
