The common logarithm of input variable x1 is formed.
LG10 provided the logarithm of a number to base 10.
If x1 is not wired, this is interpreted as x1 = 1. In this case, y1 is 0.
With a negative input variable x1, y1 = -1,5

Note:
LG10 is the reversal function of function 10EXP.
Examples:
The result of input value x1 = 63 is an output value of y1 = 1,799340549.
The result of an input value x1 = 2,71828182845904 is an output value of y1 = 1.
