FUNCTION
The following functions can be used in formulas:
LOG10 Log Base 10 ALOG Anti Log
ALOG10 Anti Log Base 10 LOG Log
AB Absolute Value SQRT Square Root
PWR Power
EXAMPLES
LOG10- Log Base 10-
Log10 2 = 0.301029995
ALOG- Anti Log- ALOG (0.69314718) = 2
ALOG10- Anti Log Base 10-
ALOG10 (0.30102995) = 2
LOG- Log- LOG 2 = 0.69314718
AB- Absolute Value- AB (-1) = 1 SQRT- Square Root- SQRT 2 = 1.4142
PWR- Power- (10 PWR 2) = 100
