Function closeToFunc

Export assertion functions

closeToFunc<R>(
    this: IAssertScope,
    expected: number,
    delta: number,
    evalMsg?: MsgSource,
): R
Asserts that the target is a number close to the given number within a specified delta. This is useful for floating-point comparisons where exact equality is not guaranteed.
Type Parameters
- R
Parameters
- this: IAssertScope
  The assert scope.
- expected: number
  The expected number to compare against.
- delta: number
  The maximum allowed difference between actual and expected. Note: A negative delta will never result in a passing assertion since the absolute difference is always non-negative.
- OptionalevalMsg: MsgSource
  The message to display if the assertion fails.
Returns R
- The assert scope.

0.1.5
Example
```
import { assert } from "@nevware21/tripwire";

assert(1.5).is.closeTo(1.0, 0.5);     // Passes - difference is 0.5
assert(10).is.closeTo(20, 20);        // Passes - difference is 10
assert(-10).is.closeTo(20, 30);       // Passes - difference is 30
assert(2).is.closeTo(1.0, 0.5);       // Fails - difference is 1.0
assert([1.5]).is.closeTo(1.0, 0.5);   // Fails - not a number
```
