Failing that, bit-shifting is insufficient to convert a 16-bit float and a 32-bit float (assuming IEEE-754 binary style formats). The 16-bit exponent bias is 15, and the 32-bit exponent bias is 127. So, if the exponent is normal, you must add 112 to its encoding. If it is subnormal, you have to find the leading 1 in ...
