LOG10()
 Computes the common logarithm
------------------------------------------------------------------------------
 Syntax

     LOG10(<nValue>) --> nLog10

 Argument

     <nValue>  Designates a number for which the base 10 logarithm is
     determined.

 Returns

     LOG10() returns the base 10 logarithm for the <nValue> number.

 Description

     LOG10() determines the common logarithm for a number.

 Note

     .  For non-mathematicians, look at it this way:  to what power
        must 10 be raised (10n) so that <nValue> results?

 Example

     Display common logarithm values:

     ? LOG10(0.01)            // -2.00
     ? LOG10(2)               //  0.30
     ? LOG10(100)             //  2.00
     ? LOG10(INFINITY())      //  308.25
