This transfer is possible in two ways: direct transfer and using the decimal system.
first, let\'s make a direct transfer.
let\'s do a direct translation from hexadecimal to binary like this:
FFFFFFFFFFFF16 = F F F F F F F F F F F F = F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) F(=1111) = 1111111111111111111111111111111111111111111111112
answer: FFFFFFFFFFFF16 = 1111111111111111111111111111111111111111111111112
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
15∙1611+15∙1610+15∙169+15∙168+15∙167+15∙166+15∙165+15∙164+15∙163+15∙162+15∙161+15∙160 = 15∙17592186044416+15∙1099511627776+15∙68719476736+15∙4294967296+15∙268435456+15∙16777216+15∙1048576+15∙65536+15∙4096+15∙256+15∙16+15∙1 = 263882790666240+16492674416640+1030792151040+64424509440+4026531840+251658240+15728640+983040+61440+3840+240+15 = 28147497671065510
got It: FFFFFFFFFFFF16 =28147497671065510
