Convert from IBM floating point to IEEE floating point standard and Vice Versa- In C#?

Question

Was looking for a way to IEEE floating point numbers to IBM floating point format for a old system we are using.

Is there a general formula we can use in C# to this

Answer 1

I recently had to convert one float to another. It looks like XDR format uses an odd format for its floats. So when converting from XDR to standard floats, this code did it.

#include 

// Read in XDR float array, copy to standard float array
// out array needs to be allocated before the function call

bool convertFromXdrFloatArray(float *in, float *out, long size)
{
    XDR xdrs;
    xdrmem_create(&xdrs,(char *)in, size*sizeof(float), XDR_DECODE);

    for(int i = 0; i < size; i++)
    {
        if(!xdr_float(&xdrs, out++)) {
            fprintf(stderr,"%s:%d:ERROR:xdr_float\n",__FILE__,__LINE__);
            exit(1);
        }
    }
    xdr_destroy(&xdrs);

    return true;
}
