+Summary:        Header for division via fixed-point math
+Name:           fxdiv
+License:        MIT
+Version:        1.0^git%{date0}.%{shortcommit0}
+Release:        5%{?dist}
+ 
+# Only a header
+BuildArch:      noarch
+ 
+URL:            https://github.com/Maratyszcza/%{name}
+Source0:        %{url}/archive/%{commit0}/%{upstream_name}-%{shortcommit0}.tar.gz

+BuildRequires: cmake
+BuildRequires: gcc-c++
+BuildRequires: gtest-devel
+ 
+%description
+Header-only library for division via fixed-point multiplication by inverse
+ 
+On modern CPUs and GPUs integer division is several times slower
+than multiplication. FXdiv implements an algorithm to replace an
+integer division with a multiplication and two shifts. This
+algorithm improves performance when an application performs repeated
+divisions by the same divisor.
+ 
+Features
+  * Integer division for uint32_t, uint64_t, and size_t
+  * Header-only library, no installation or build required
+  * Compatible with C99, C++, OpenCL, and CUDA
+  * Uses platform-specific compiler intrinsics for optimal performance
+  * Covered with unit tests and microbenchmarks
+
