chop is a MATLAB function for rounding the elements of a matrix to a lower precision arithmetic with one of several forms of rounding. Its intended use is for simulating arithmetic of different precisions (less than double) with various rounding modes. The input to chop should be single precision or double precision and the output will have the same type: the lower precision numbers are stored within a higher precision type.

The arithmetic formats supported are

'b', 'bfloat16' - bfloat16,
'h', 'half', 'fp16' - IEEE half precision (the default),
's', 'single', 'fp32' - IEEE single precision,
'd', 'double', 'fp64' - IEEE double precision,
'c', 'custom' - custom format.
