How do I set the floating point precision in Perl?

Question

Is there a way to set a Perl script\'s floating point precision (to 3 digits), without having to change it specifically for every variable?

Something similar to TCL\

Answer 1

I wouldn't recommend to use sprintf("%.3f", $value).

Please look at the following example: (6.02*1.25 = 7.525)

printf("%.2f", 6.02 * 1.25) = 7.52

printf("%.2f", 7.525) = 7.53
