Returns the base 10 log of x (x positive only).
The argument value is restricted for log, log10, and sqrt.
log10(x) (no rate restriction)
where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.
Here is an example of the log10 opcode. It uses the files log10.orc and log10.sco.
Example 206. Example of the log10 opcode.
/* log10.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 i1 = log10(8) print i1 endin /* log10.orc */
/* log10.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* log10.sco */
Its output should include a line like this:
instr 1: i1 = 0.903
