From 0d5196feadafa77c727f517d747ffcf3fd0e8ba9 Mon Sep 17 00:00:00 2001 From: Michael Hudson-Doyle Date: Wed, 13 Mar 2019 15:55:30 +1300 Subject: [PATCH] round result of (highest as f64).log(2.0) Even though (1024f64).log(2.0) has an exact, representable, value, with rustc 1.32 on i386 it comes out as +9.999999999999999985 with optimization enabled. And the rustc doesn't like having two defintions for U1024 etc. --- build/main.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git rustc-1.35.0-src/vendor/typenum/build/main.rs rustc-1.35.0-src/vendor/typenum/build/main.rs index 16b0ffe2f..b7939f993 100644 --- rustc-1.35.0-src/vendor/typenum/build/main.rs +++ rustc-1.35.0-src/vendor/typenum/build/main.rs @@ -81,7 +81,7 @@ pub fn no_std() {} fn main() { let highest: u64 = 1024; - let first2: u32 = (highest as f64).log(2.0) as u32 + 1; + let first2: u32 = (highest as f64).log(2.0).round() as u32 + 1; let first10: u32 = (highest as f64).log(10.0) as u32 + 1; let uints = (0..(highest + 1)) .chain((first2..64).map(|i| 2u64.pow(i))) --- rustc-1.35.0-src/vendor/typenum/.cargo-checksum.json +++ rustc-1.35.0-src/vendor/typenum/.cargo-checksum.json @@ -1 +1 @@ -{"files":{"CHANGELOG.md":"caf37574d41c38570e892c4fed38cbc2fd22794ec512949c1f0faad1d866fced","Cargo.toml":"58822547c70a09449e6a069e6c197423a9e471d993ebf4ea20101e042781edf7","LICENSE":"a825bd853ab71619a4923d7b4311221427848070ff44d990da39b0b274c1683f","README.md":"7a19a1fb2f219fbc270535e0fee2caa96968b976cd74d33d12e2f2ef436d0895","build/main.rs":"44d33ee79a76a90a769096547ba4c7a5d3822afffeed025dfbcc5bb755227d52","build/op.rs":"a393b6818384a50688db8cb923891f86ccce39a9dccbf7c684efb9bef83b4acf","build/tests.rs":"a04fd3185ea8b19c36cb939178e5fedf16b4b36c2df0a2e79593339d998bd1ce","src/array.rs":"7243dbe44f3818c852c67bd0c3af14d57473fb9c3efda2c0d98251b3fe8b4d57","src/bit.rs":"023f9f6768331ac17de72b6248c6a9d6a7b856842f56067c9c1e04b729ed9e04","src/int.rs":"de4c49717a7a40572e579fad2380f29698c5571844ff1462e368531072dba55e","src/lib.rs":"2a58ff8553851eb6b9d7fa70315d688431dd0573f8491e53cfe799a092347b96","src/marker_traits.rs":"abf73f3930b5129d01aaa64c51275c4ca4ce0ef8961f7a9e744ee731d6308200","src/operator_aliases.rs":"43eb6a29dc0387ec329df5d9af0b4479a1301b3a9b2304c3b7b7d8c03e01ff5d","src/private.rs":"48c572aa27bd444062eadb4bd3f5ca38c1e6efb66bc074f38555499b33f0dcaf","src/type_operators.rs":"df9ef3ae2a69d56258db41f8166342a65f6e4085581709140719d1b7e3916bb9","src/uint.rs":"df4fdad3110a7e08fdc21e49f7e82fd525d6a78fcf904a766729aa47c0200727","tests/test.rs":"1e559fadf0af1a38d7049caef26e3a162c58ea5e024aa637299376d776986549"},"package":"612d636f949607bdf9b123b4a6f6d966dedf3ff669f7f045890d3a4a73948169"} \ No newline at end of file +{"files":{"CHANGELOG.md":"caf37574d41c38570e892c4fed38cbc2fd22794ec512949c1f0faad1d866fced","Cargo.toml":"58822547c70a09449e6a069e6c197423a9e471d993ebf4ea20101e042781edf7","LICENSE":"a825bd853ab71619a4923d7b4311221427848070ff44d990da39b0b274c1683f","README.md":"7a19a1fb2f219fbc270535e0fee2caa96968b976cd74d33d12e2f2ef436d0895","build/main.rs":"38a90c85068bb6bba1d21e9d5976e693b9b868ed0c16b26986332d2ca1c01047","build/op.rs":"a393b6818384a50688db8cb923891f86ccce39a9dccbf7c684efb9bef83b4acf","build/tests.rs":"a04fd3185ea8b19c36cb939178e5fedf16b4b36c2df0a2e79593339d998bd1ce","src/array.rs":"7243dbe44f3818c852c67bd0c3af14d57473fb9c3efda2c0d98251b3fe8b4d57","src/bit.rs":"023f9f6768331ac17de72b6248c6a9d6a7b856842f56067c9c1e04b729ed9e04","src/int.rs":"de4c49717a7a40572e579fad2380f29698c5571844ff1462e368531072dba55e","src/lib.rs":"2a58ff8553851eb6b9d7fa70315d688431dd0573f8491e53cfe799a092347b96","src/marker_traits.rs":"abf73f3930b5129d01aaa64c51275c4ca4ce0ef8961f7a9e744ee731d6308200","src/operator_aliases.rs":"43eb6a29dc0387ec329df5d9af0b4479a1301b3a9b2304c3b7b7d8c03e01ff5d","src/private.rs":"48c572aa27bd444062eadb4bd3f5ca38c1e6efb66bc074f38555499b33f0dcaf","src/type_operators.rs":"df9ef3ae2a69d56258db41f8166342a65f6e4085581709140719d1b7e3916bb9","src/uint.rs":"df4fdad3110a7e08fdc21e49f7e82fd525d6a78fcf904a766729aa47c0200727","tests/test.rs":"1e559fadf0af1a38d7049caef26e3a162c58ea5e024aa637299376d776986549"},"package":"612d636f949607bdf9b123b4a6f6d966dedf3ff669f7f045890d3a4a73948169"}
