FMath: MIX_FLOATS_2_ARGS
#include "Templates/ResolveTypeAmbiguity.h"
Access: public
Description
Preprocessor macro that injects a two-argument template overload for mixing float/double/integral argument types, promoting all arguments to the highest-precision floating-point type.
Caveats & Gotchas
- • Like MIX_FLOATS_3_ARGS, this is a code-generation macro, not a real function. It only fires when at least one argument is a floating-point type and the two arguments are not the same type.
- • Be aware that integer-only calls to functions decorated with this macro are not covered by the mixed overload — e.g. GridSnap(int32, int32) resolves to the existing template, not a float conversion.
Signature
MIX_FLOATS_2_ARGS(Func)Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| Func | identifier | The name of the existing two-argument template function to generate mixed-type overloads for. | — |
Example
Using the mixed-type GridSnap it enables C++
// Enabled by MIX_FLOATS_2_ARGS(GridSnap) inside FMath:
double Snapped = FMath::GridSnap(3.7, 1.0f); // double + float -> doubleTags
