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 (Epsilon*) of each other.

See Mathf.Approximately in Unity3D documentation

*Epsilon is defined as: The smallest value that a float can have different from zero.
