Returns the truncated base 10 logarithm of the argument.
"...The integer which is the exponent of the magnitude
of the most significant digit of the operand.
(As though the operand were truncated to a single digit
while maintaining the value of that digit and without
limiting the resulting exponent)". (p. 47)
