Example 22. Example of the abs opcode.
/* abs.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 i1 = -6 i2 = abs(i1) print i2 endin /* abs.orc */
/* abs.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* abs.sco */
Its output should include lines like:
instr 1: i2 = 6.000
