IMLOG2(value)

Part Description Notes
value The input value of the logarithm function.
  • The number can be written as plain numbers, for example 1, to be interpreted as a real number.
  • The number can be written as quoted text in order to specify both the real and complex coefficients.

Sample formulas 

IMLOG2("1+i", 3.5)

IMLOG2(COMPLEX(25, 34), 2.3)

IMLOG2(100, 10)

Notes

IMLOG2 is equivalent to IMLOG given base of 2 for all numbers.
