====== approximately ======
approximately(<-val1 <-val2)

===== Description =====
Compares two floating point values and returns true if they are similar.

Floating point imprecision makes comparing floats using the equals operator inaccurate. For example, (1.0 == 10.0 / 10.0) might not return true every time. Approximately() compares two floats and returns true if they are within a small value (//Epsilon//((Epsilon is defined as: The smallest value that a float can have different from zero.))) of each other.

See [[https://docs.unity3d.com/Documentation/ScriptReference/Mathf.Approximately.html | Mathf.Approximately in Unity3D documentation]]

If you came to this documentation for an API to handle an approximation that's much larger than (//Epsilon//((Epsilon is defined as: The smallest value that a float can have different from zero.))), such as comparing 1.625002 to 1.625000, an alternative is to use [[4rpl:commands:distance|Distance]] and define your own approximation margin.

===== Examples =====
<code 4rpl>
if (approximately(1.000001 1))
    trace("1.000001 is approximately equal to 1")
endif
