The given hexadecimal number is F12A.17B.

To convert hexadecimal to decimal, we need to multiply each digit by the corresponding power of 16 and sum them up.

(F * 16^3) + (1 * 16^2) + (2 * 16^1) + (A * 16^0) + (1 * 16^-1) + (7 * 16^-2) + (B * 16^-3) = (15 * 16^3) + (1 * 16^2) + (2 * 16^1) + (10 * 16^0) + (1 * 16^-1) + (7 * 16^-2) + (11 * 16^-3)

Calculating the above expression gives us the decimal equivalent of the hexadecimal number: 38858.0985
