fName=NameFrequency(fValue, [numDecimalPlaces])

NameFrequency accepts a frequency (in Hz) and returns a
string naming that frequency in a more readable form. For example:

\>\> c=[Screen](Screen)('Computer');  
\>\> c.hw.cpufreq  
  
ans =  
  
   999999997  
  
\>\> [NameFrequency](NameFrequency)(c.hw.cpufreq)  
  
ans =  
  
1.00 [GHz](GHz)  
  
\>\> [NameFrequency](NameFrequency)(c.hw.cpufreq,6)  
  
ans =  
  
999.999997 [MHz](MHz)  
  
\>\>  

By default NameFrequency displays two digits to the right of the decimal
point. Specify other numbers of digits by passing the optional
numDecimalPlaces argument.

NameFrequency is used by DescribeComputer to name the clock frequency of
the CPU. For that purpose, it displays frequency to a specified number of
decimal places, not to a specified precision. It is therfore a poor
choice for scientific work, where typcially a fixed precision in digits
is appropriate.
