# logarithmic functions

This subchapter looks at logarithmic functions.

ALGOL    ln(E) — ALGOL-60 library function that returns the natural logarithm of an expression.
Pascal    ln(x) — Pascal standard function that returns the REAL natural logarithm of an argument x (X > 0).

ALGOL    exp(E) — ALGOL-60 library function that returns the exponential of an expression.
BASIC    EXP(x) — BASIC library function that returns the value of the natural number e raised to the power specified by an expression.
Pascal    exp(x) — Pascal standard function that returns the REAL e (logarithmic natural number) raised to the power of an argument x.

“42.1/2 The predefined standard library packages provide facilities such as string manipulation, containers of various kinds (vectors, lists, maps, etc.), mathematical functions, random number generation, and access to the execution environment.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary See legal information

# free music player coding example

Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
