       frexpd64(), frexpd128(), frexpd32() - extract mantissa and exponent from decimal floating-point numbers

SYNOPSIS

DESCRIPTION

       The  function  breaks  a  decimal floating-point number into a normalized decimal fraction f and an integral power of 10.  It returns f and
       stores the integer exponent of 10 in the object pointed to by exp.  The fraction f is a with magnitude in the interval [0.1,  1)  or  zero,
       and value equals f times 10 raised to the power *exp.

       is a version of it takes a first argument and returns a result.
