mnchartier Posted May 8, 2007 Share Posted May 8, 2007 Trying to create some small scripts for audio calculations and I am using the log function but it is not always correct. If you use the sample in the help file it comes out right but I am trying this $Log1 = log(4) $Log2 = log(8) consolewrite ($log1) consolewrite (@CRLF) consolewrite ($log2) and they do not come out correctly, they are coming out 1.38629436111989 and 2.07944154167984 respectively and they should be 0.6021 and 0.90309. Any one else use log and have similar problems? Link to comment Share on other sites More sharing options...
PsaltyDS Posted May 8, 2007 Share Posted May 8, 2007 You didn't read the help file closely enough. The AutoIt log() function, and those of most programming languages, return the nautural log, or ln(x), or loge(x). You are looking for common log, or log10(x):ConsoleWrite("log(4) = " & Log(4) & @LF) ConsoleWrite("Log10(4) = " & Log10(4) & @LF) ConsoleWrite("log(8) = " & Log(8) & @LF) ConsoleWrite("Log10(8) = " & Log10(8) & @LF) ; user-defined function for common log Func Log10($x) Return Log($x) / Log(10) ;10 is the base EndFunc ;==>Log10 Valuater's AutoIt 1-2-3, Class...
