The print opcode will truncate decimal places and may not show the complete value. Csound's precision depends on whether it is the floats (32-bit) or double (64-bit) version, since most internal calculations use one of these formats. If you need more resolution in the console output, you can try printf. |
Here is an example of the print opcode. It uses the file print.csd.

Its output should include lines like this:
instr 1: p4 = 50.375 instr 1: p4 = 300.000 instr 1: p4 = -999.000
