NAME

       quantexpd64(), quantexpd128(), quantexpd32() - decimal quantum exponent functions

SYNOPSIS

DESCRIPTION

       The function computes the quantum exponent of x.

       The signed integral coefficient of x can be computed as

NAME

       quantized64(), quantized128(), quantized32() - decimal quantize functions

SYNOPSIS

DESCRIPTION

       The  function sets the exponent of x to the exponent of y, while attempting to keep the value the same. If the exponent is being increased,
       the value is correctly rounded according to the current (decimal) rounding mode.

       is useful for rounding to a specified number of decimal places.	For example, will round x to four places to the right of the decimal point
       (provided the has enough digits to do so).

RETURN VALUE

       If  the	exponent of x is being increased and rounding produces a result whose numerical value is different from x, then raises the inexact
       exception.

       If the exponent of x is being decreased and the of the result has more digits than the type would allow, returns NaN and raises the invalid
       exception.

       If one or both arguments are NaN, then returns NaN.

       Otherwise, if only one argument returns NaN and raises the invalid exception.

       If both arguments returns x.

ERRORS

       No errors are defined.
