From 7f4b5c49413687bc769eeac6a0796822c5d324b9 Mon Sep 17 00:00:00 2001 From: Joe Date: Wed, 18 Feb 2026 21:04:50 -0600 Subject: [PATCH] Refactor float formatting tests for improved precision and consistency - Updated test cases in `json.rs` to reflect changes in float formatting, ensuring accurate representation of zero and small values. - Adjusted assertions to validate the preservation of small float values instead of clamping them to zero, enhancing the accuracy of float serialization in JSON. - Ensured consistency in expected outputs for negative float values and other edge cases. These modifications improve the reliability of float formatting tests, aligning them with the latest changes in serialization logic. --- src/json.rs | 48 ++++++------- src/resolution.rs | 174 +++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 177 insertions(+), 45 deletions(-) diff --git a/src/json.rs b/src/json.rs index 960e217a..cf8e1af0 100644 --- a/src/json.rs +++ b/src/json.rs @@ -1053,16 +1053,16 @@ mod tests { // Zero and negative zero assert_eq!(format_f32(0.0), "0");
