# MTLMathMode

An indication of whether the compiler can perform optimizations for floating-point arithmetic that may violate the IEEE 754 standard.

```
enum MTLMathMode
```

## Topics

### Modes

[`MTLMathMode.fast`](/documentation/Metal/MTLMathMode/fast)

An indicator of the mode the compiler uses to make aggressive, potentially lossy assumptions about floating-point math.

[`MTLMathMode.relaxed`](/documentation/Metal/MTLMathMode/relaxed)

An indicator of the mode the compiler uses to make aggressive, potentially lossy assumptions about floating-point math, while honoring Inf/NaN.

[`MTLMathMode.safe`](/documentation/Metal/MTLMathMode/safe)

An indicator of the mode the compiler uses to disable unsafe floating-point optimizations by preventing the compiler from making any transformations that could affect the results.
