NAME

       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.

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

       These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward.

USAGE

       To use any of these functions, compile with the option.

       Make sure your program defines and then includes

       Link in the math library by specifying or on the linking command line.

       For more information, see the at the following site:

RETURN VALUE

       If value is zero, returns value and stores zero in the object pointed to by exp.

       If value is NaN, returns NaN, and the value of *exp is unspecified.

       If value returns value, and the value of *exp is unspecified.

       These functions raise no exceptions.

ERRORS

       No errors are defined.
