Data Result Transfer formula
Here we have to process “81f4” as conveyed
· 1f4 = 500 (Characteristic)
· 8 = 8 (Base)
· For Mentissa
o 8 = 1000 (binary)
o First bit = 1 (-ve)
1’s component of 1000 = 0111
2’s complement of 1000 = 0111+1 = 1000 = 8 (decimal)
0x81f4 = 500 * (10 ^ -8) = 0.000005 kg/L = 0.5 mg/dL
For example:
A276 = 0x276 * 10^(2’s complement of 0x0a) = 630 * 10^(-6) = 0.00063 kg/l = 63mg/dl
B11b = 0x11b * 10^(2’s complement of 0x0b) = 283 * 10^(-5) = 0.00283 mol/l = 2.83 mmol/l
