$MinPrecision
 Usage
Notes
 Further Examples
The default value of $MinPrecision is  .
In[1]:=
|
Out[1]=
|
Numbers with negative precision are meaningful. They indicate that the numbers are swamped by error.
In[2]:=
|
Out[2]=
|
This defines the function FixedPrecisionEvaluate which locally resets the values of $MinPrecision and $MaxPrecision before evaluating its input.
In[3]:=
|
In[4]:=
|
The precision of the result is the same as the precision of the input.
In[5]:=
|
Out[5]=
|
In contrast, significance arithmetic dynamically adjusts precision according to the precision of the inputs. The precision of the result is one binary bit less precise.
In[6]:=

Out[6]=
