The One Operand Calculator Program

 

This program allows for the calculation of base 10 logarithms. Most of the time you would use a log table to look up the base 10 logarithm of a number greater than zero. However, it is easy to know the base 10 logarithm of a number that is a power of 10. For example:

log10 10 == log10 101 = 1

log10 100 == log10 102 = 2

log10 1000 == log10 103 = 3

log10 1,000 == log10 104 = 4

log10 10,000 == log10 105 = 5

and so on.

Please note that the log100 is undefined.
