Int32 to sc_fixed

[pilipovicn]

    I receive an integer from an external API, that is actually a fixed point real value, disguised as int for transport compatibility. I need to convert the integer back into it's fixed point representation. I presume I can convert the int to sc_bv. Then, I would expect sc_fixed to have a constructor accepting a sc_bv, and specify the decimal point place through sc_fixed template.

    Looking through the source, It seem though that sc_fixed cannot be constructed from a sc_bv. The closest thing I see is the char* constructor (pass bits using sc_bv.to_string() ), but I'm pretty sure that converts a decimal string, not a binary string.

    In short, is there a simple enough way to convert the bits of an integer (in the form of sc_bv) into a real number (say, float) by specifying the fixed point location in the bit vector?

How about constructing an sc_fxval from your integer, shifting then its value to the right by the amount of fractional digits and then constructing your sc_fixed variable with fixed number of bits from it?
