Functions

clamp(value, min, max)

@spec clamp(value :: float(), min :: float(), max :: float()) :: float()

Clamp float value

epsilon()

A floating point 'good enough' threshold for comparison checks

float_equals(x, y)

@spec float_equals(x :: float(), y :: float()) :: boolean()

Check whether two given floats are almost equal.

Exray developer note: "Meh, looks close enough :^)"

lerp(start, stop, amount)

@spec lerp(start :: float(), stop :: float(), amount :: float()) :: float()
