Commit ID a0cc15ccbc5dc48ea3c871915c8f96c7a624597d
Author Lucas Braesch
Date 2013-10-05 16:12:52 UTC
Use double everywhere Rationale: - Speed of double and float is about the same (not on the hot path anyway) - Double makes code prettier (no need to write 1.0f, just 1.0) - Only practical advantage of float is to use less memory, but since we never store large arrays of double, we don't care. No functional change.
