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 |

Its output should include lines like these:
instr 1: irand = 2.930
instr 1: irand = 0.420
instr 1: irand = 2.316
