scaling
Property of a decimal floating point number .
A decimal floating point number can be seen as an integer number of a
predefined length that is scaled by dividing through a power of ten.
This defines the number of decimal
places . In this sense, the negative exponent of a decimal floating
point number is called scaling that applies to the mantissa. For positi
ve scaling, it is equivalent to the number of decimal places. Decimal
floating point numbers with the same value can have different scaling.
Operations on decimal floating point numbers usually are given the
scaling and thus the number of decimal places. One
predefined function for changing
the scaling is rescale .
