# safeStep(maxValue:maxCompression:)

Returns a time delta small enough to represent a jump discontinuity, but large enough to survive scaling and shifting without collapsing to zero.

## Declaration

```swift
static func safeStep(maxValue: Double = 1e6, maxCompression: Double = 10.0) -> Double
```

## Discussion

Discussion Use it to author paired samples at t and t + SafeStep() that stay distinct for any t in [-maxValue, maxValue] under compression up to maxCompression. Equivalent to: epsilon * maxValue * maxCompression * 2..
