Converting decimal to/from IEEE hex format

Can anyone tell me how to convert a number to/from the corresponding IEEE hex floating-point representation in either 32 or 64 bits in Mathematica? For example, I would want to convert 1.0 into 3F800000 (32-bit) or 3FF0000000000000 (64-bit), and vice-versa. (When converting from decimal to hex, if the number is not exactly representable, I would want the nearest floating-point number.) Thanks, Robert
