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).

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 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
