.BI Byte.get_bit\ :\ func(i:\ Byte,\ bit_index:\ Int\ ->\ Bool)
.fi
.SH DESCRIPTION
In the binary representation of a byte, check whether a given bit index is set to 1 or not.
.SH ARGUMENTS

.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.
