Arg(z) is the principal value of the arg function; its value is restricted to (−π, π]. It can be computed using Arg( x + iy ) = atan2 ( y , x ) . Log( z ) is the principal value of the complex logarithm function and has imaginary part in the range (− π , π ] .
Graph of log 2 x as a function of a positive real number x. In mathematics, the binary logarithm (log 2 n) is the power to which the number 2 must be raised to obtain the value n.
Three-dimensional plot showing the values of the logarithmic mean. In mathematics, the logarithmic mean is a function of two non-negative numbers which is equal to their difference divided by the logarithm of their quotient. This calculation is applicable in engineering problems involving heat and mass transfer.

The activation energy Q takes a different value depending on whether the high or low temperature limit is being considered: it changes from a high value Q H at low temperatures (in the glassy state) to a low value Q L at high temperatures (in the liquid state). Common logarithm of viscosity against temperature for B 2 O 3, showing two regimes
MM2 may refer to: MM2, a class of force fields; see force field (chemistry) MM2 (MMS), an interface utilized by the Multimedia Messaging Service standard; Mega Man 2, a 1988 video game for the NES; Mega Man II, a 1991 video game for the Game Boy; Midtown Madness 2, a 2000 video game for the PC; Motocross Madness 2, a 2000 video game for the PC
In a third layer, the logarithms of rational numbers r = a / b are computed with ln(r) = ln(a) − ln(b), and logarithms of roots via ln n √ c = 1 / n ln(c).. The logarithm of 2 is useful in the sense that the powers of 2 are rather densely distributed; finding powers 2 i close to powers b j of other numbers b is comparatively easy, and series representations of ln(b) are ...
