Right on the money! "%0.f" gives me:
B5390493 0.59 1
B5390494 0.58 1
B5390495 0.54 1
B5390497 0.54 1
B5390498 0.53 1
B5700917 0.53 1
B5700918 0.54 1
Which is what I wanted.
The sprintf documentation in the perlfunc manpage is quite extensive.
There no problem with the docs, just my understanding of decimal and
floating point numbers.
Thanx again Tom,
Dp.
