approximately(<-val1 <-val2)

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 (Epsilon¹⁾) of each other.

See Mathf.Approximately in Unity3D documentation

If you came to this documentation for an API to handle an approximation that's much larger than (Epsilon²⁾), such as comparing 1.625002 to 1.625000, an alternative is to use Distance and define your own approximation margin.

if (approximately(1.000001 1))
    trace("1.000001 is approximately equal to 1")
endif
