Exponential and logarithm functions are a very important part of mathematics in both theory and practice. They can be used to model real-world situations, exponential functions are used to model population, compute investments, carbon date artifacts, radioactive decay, bacterial growth, cooling of objects and so on. On the other hand, logarithm functions are used in calculating interest rate, defining and expressing the unit of the power of a sound wave – decibel measures, to calculate exposure in photography, earthquakes (Richter scale), the brightness of stars, pH balance, acidity and alkalinity, and many other real life examples.

In MatDeck, exponential and logarithm functions cover all aspects using several functions that can assist and aid you to calculate complex exponential and logarithm functions lightning fast.

### These MatDeck functions are:

exp – Exponential function that uses e (Euler’s number) base

exp2 – Exponential function with number two base

expm1 – Exponential function with e (Euler’s number) base subtract one

ldexp – Multiplies a floating point argument by the number 2 raised to the exp power

frexp – Decomposes floating point argument into a normalized fraction and an integral power of two

ln – Natural logarithm (base e Euler’s number) of argument

logb – Extracts exponent from the number

log – Calculates logarithm (base 10) of argument

log2 – Calculates logarithm (base 2) of argument

logax – Calculates logarithm base a of argument x

log1p – Calculates natural logarithm (base e) of 1 + argument

pow – Calculates x to the power of n (exponential functions which base isn’t Euler’s number)

MatDeck’s 2D and 3D graphs can plot exponential and logarithm functions in real or complex planes, use exponential and logarithm regressions to model and predict different real-world situations, export and save calculations made with these functions, calculate their derivatives (numerical or symbolical) and integrals (numerical),etc.
