mostly to ease porting from std::vector, not particularly optimized

Returns the number of levels in the given ISE range.

between [l,h]

String formatting

Returns the # of endpoint values for the given CEM.

Fast high precision piecewise linear approximation of log2(bias+x). Half may be zero, positive or denormal. No NaN/Inf/negative.

returns squared length (norm)

! ZSTD_isError() : * tells if a return value is an error code * symbol is required for external callers */

init: cache columns, norms, and label set

Clamps a value between 0-255.

Configures the compressor's mode by setting the proper parameters (which were preserved for backwards compatibility with old code). This is by far the

Returned selector value ranges from 0-3 and is a direct index into g_etc1_inten_tables.

between [l,h]

Reset everything to default/uninitialized state.

Notes: qlog16_to_half(half_to_qlog16(half_val_as_int)) == half_val_as_int (is lossless) However, this is not lossless in the general sense.

resize(0) sets the container to empty, but does not free the allocated block.
