Function
The common logarithm of a binary oating-point number is calculated. The base is 10.
Note: The value in S must be positive. If it is 0 or negative, an operation error will occur. The error code is
K6706 and stored in D8067. The error ag M8067 is set to ON to identify this error.
Example:
M10
ǒDLOG10 D0 D2Ǔ
S D
M11
When M10 = ON, the common logarithm of the binary floating-point
number in (D1, D0) is calculated with a base of 10.
