Test-Number-Delta (1.03) *****

A useful solution to a common problem.

There's a world of difference between

ok( $number >= 9 and $number <= 11 );


delta_within( $number, 10, 1 );

particularly when it comes coupled with appropriate error messages.

Test-Number-Delta (1.01) *****

I am currently using this module extensively in my application project and am finding it a delight to use. I recently requested some additions to the module to handle floating-point array comparisons. The author was very quick to respond and not only implemented array comparisons but went a step further to also implement FP matrix comparisons. My conversations with the author were very pleasant and I thoroughly recommend his Test::Number::Delta module for FP comparisons.
