*Where <math>n</math> is a positive real number and
*<math>Number</math> is a positive real number and
*<math>base</math> is the base of the logarithm.
*<math>Base</math> is the base of the logarithm.
LOG() determines the logarithm of a number to a specified base.
LOG() returns the logarithm of a number to a specified base.

LOG(n, base)
LOG(Number,Base)
For Example,
For Example,
LOG(4, 0.5) ''returns -2''
LOG(4, 0.5) ''returns -2''
*The number <math>n</math> should be a positive real number. Else Calci displays NaN error message.
*The <math>Number</math> should be a positive real number. Else Calci displays NaN error message.
*The <math>base</math> should be a positive real number. Else Calci displays NaN error message.
*The <math>Base</math> should be a positive real number. Else Calci displays NaN error message.
*If the <math>base</math> is omitted, Calci assumes it to be 10.
