Syntax:
LOG(x:number {, b:number})
Returns gives the base ten logarithm of x.
x must be > 0
.
Example:
LOG(64)
returns the number 1.80618
.
Starting with 2.00, this function will accept an extra numeric parameter,
b (optional), which then
returns the logarithm of x to base b.
If b is omitted, the logarithm of x to base ten is returned as before.
