I'm sorry I mistake the function name, the function is
floatToRawIntBits(), it convert ieee 754 floating point number to
integer,  e.g. if f1>f2 then floatToRawBits(f1) > floatToRawBits(f1)
I want convert floating point number to sortable string to index in
Lucene, so I want first to conver the floating point number to integer
first, and than convert the integer to sortable string?

so How to convert a ieee 754 floating point to raw bits like the java
api floatToRawBits do?

Appreciate your help!
