<masak> rn: say sprintf '%12.5f', Inf
<p6eval> niecza v24-12-g8e50362: OUTPUT«    Infinity␤»
<p6eval> ..rakudo f5037e: OUTPUT«Inf␤»
<masak> rn: say sprintf '%12.5f', -Inf
<p6eval> rakudo f5037e: OUTPUT«-Inf␤»
<p6eval> ..niecza v24-12-g8e50362: OUTPUT«   -Infinity␤»

Modulo Niecza's preference for "Infinity" instead of "Inf", I believe
Niecza's outputs are correct each time, and Rakudo's are wrong. The
default for sprintf directives is to right-justify. This works fine
with numbers, but not with the special values NaN, Inf, and -Inf.

<masak> rn: say sprintf '%12.5f', 42
<p6eval> rakudo f5037e, niecza v24-12-g8e50362: OUTPUT«    42.00000␤»
