May be I should give more detailed description about the problem. When I evaluate J0(0) (Zero-order Bessel function at x=0), I get 1.0000000028314100 instead of the theoretical value 1.000000000000000000...... The same applies to other values of x and, in general, the output is only valid up to single precision.
I use Labview 6.1 on WinXP system.
