+.SH DESCRIPTION
+In the binary representation of a byte, check whether a given bit index is set to 1 or not.

+l l l l.
+Name	Type	Description	Default
+i	Byte	The byte whose bits are being inspected. 	-
+bit_index	Int	The index of the bit to check (1-indexed, range 1-8). 	-
+.TE
+.SH RETURN
+Whether or not the given bit index is set to 1 in the byte.
+
+.SH NOTES
+The bit index must be between 1-8 or a runtime error will be produced.

+.SH LIBRARY
+Tomo Standard Library
+.SH SYNOPSIS

+.SH DESCRIPTION
+In the binary representation of an integer, check whether a given bit index is set to 1 or not.

+.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.
