151 as an 8-bit signed binary number -


converting base 10 base 2 n = 8

a= 49 b= 151

by doing 49 00110001 , -49 11001111.

i having problems finding 151 , -151 because after conversion 8-bit number. 151 10010111, in signed binary doesn't farthest left digit indicate whether negative or positive. 1 negative , trying positive 151, within 8-bits. how go this?

if have 8 bits, unsigned range 0 255, makes signed range -128 127. cannot express -151 or 151 signed number 8 bits.
