From aa51343df48c06aa47805ade85c19402be3f2c49 Mon Sep 17 00:00:00 2001 From: David Mak Date: Thu, 2 Nov 2023 14:56:35 +0800 Subject: [PATCH] core: Revert breaking changes to round-family functions These functions should return ints as the math.* functions do instead of following the convention of numpy.* functions. --- nac3core/src/toplevel/builtins.rs | 184 ++++++++++++++++++++++++-- nac3standalone/demo/interpret_demo.py | 17 ++- nac3standalone/demo/src/math.py | 36 ++++- 3 files changed, 223 insertions(+), 14 deletions(-) diff --git a/nac3core/src/toplevel/builtins.rs b/nac3core/src/toplevel/builtins.rs index 46c8a1ba..f2d59b54 100644 --- a/nac3core/src/toplevel/builtins.rs +++ b/nac3core/src/toplevel/builtins.rs @@ -737,6 +737,66 @@ pub fn get_builtins(primitives: &mut (PrimitiveStore, Unifier)) -> BuiltinInfo { )))), loc: None, })), + create_fn_by_codegen( + primitives, + &var_map, + "round", + int32, + &[(float, "n")], + Box::new(|ctx, _, _, args, generator| { + let llvm_f64 = ctx.ctx.f64_type();
