alternative workaround using a multiplication instead of a division

#ifdef FIX_FLOAT_1544_SBA_META_IMPRECISION_UNSAFE_MATH

    /*

       The expression ceilf( (float) *metadata_max_bits * nbands / 5 ) was converted to double precision because of issues with -funsafe-math-optimizations,

       where an imprecision of the division in combination with the ceilf()-operator could actually produce different results (+1) for *metadata_max_bits.

       Alternative ways to address this:

       1) Pick up the corresponding code from the BASOP codebase

       2) An expression which takes care of small imprecisions of the division, e.g., ceilf( ( (float) *metadata_max_bits * nbands / 5 ) - 0.1f )

          (minimum non-zero fractional part for X / 5 is 0.2 - substract half of this, to compensate for imprecisions; the ceilf() should still return the correct integer)

       For reasons of code-readability, the variant with double precision was chosen.

      original formula was:

      *metadata_max_bits = (int16_t) min( (float) MAX16B, ceilf( (float) *metadata_max_bits * nbands / 5 ) );

      The division by 5 is replaced by a multiplication by 0.2f, since the division is causing problems for

      certain optimizations using -funsafe-math-optimizations

    */

    *metadata_max_bits = (int16_t) min( (float) MAX16B, ceilf( (float) ( (double) *metadata_max_bits * nbands / 5 ) ) );

    *metadata_max_bits = (int16_t) min( (float) MAX16B, ceilf( *metadata_max_bits * nbands * 0.2f ) );

#else

    *metadata_max_bits = (int16_t) min( (float) MAX16B, ceilf( (float) *metadata_max_bits * nbands / 5 ) );
