Subject: [PATCH] test-path-utils: use a C89 compatible format for double printf
Date: Mon,  9 Aug 2021 00:25:51 -0700	[thread overview]
Message-ID: <20210809072551.94391-1-carenas@gmail.com> (raw)
In-Reply-To: <20210809063004.73736-1-carenas@gmail.com>

a62f9d1ace (test-path-utils: offer to run a protectNTFS/protectHFS
benchmark, 2019-09-04) add a tool for testing that uses a double
variable to keep track of time but prints them with "%lf".

while correct for newer C standards, it is not defined in C89 and
it is not needed, since both float and double will be promoted to
double by printf and should therefore use "%f"; change it accordingly.
