LOGTEN(<expN>)
 Provides access to decimal rather than the natural logarithm.
 Returns <expN> logarithm of <expN> to the base 10.

 Returns the power to which 10 must be raised in order to produce <expN>.

 This is a specialized case of LOGNBASX(), where <base>
 in LOGNBASX() is 10 by definition.

 * To what power of 10 is INFINITY() equivalent?
 m_infin = INFINITY()
 m_bigten = LOGTEN(m_infin)  && returns 308.25
