The LG10 and LG10P instructions are logarithmic instructions. The LG10 instruction calculates the common logarithm function of S1 and stores the result in D1.
For the result in D1, the result of log10S1 is output as a real value.
Equation: D1 = log10S1
The LG10 and LG10P instructions always pass power. When using the LG10 and LG10P instructions, an error will occur if the variables specified in operands S1 and D1 are not of the same type. Designate the same variable type in all operands S1 and D1.
Refer to the following for specifying a constant.
When operand D1 is a float variable
When 0f (zero and lower case "f") is input, the following values are interpreted as float values.
When operand D1 is a real variable
When 0r (zero and lower case "r") is input, the following values are interpreted as real values.
When calculating data in a specified array
Specify the array using Data [0] or Data [N] (N indicates an integer variable).
When operands S1 and D1 specify the entire array, an error will occur even if the specified variables are the same type.
