java.lang.Object

zserio.runtime.FloatUtil

public final class FloatUtil
extends java.lang.Object

The class provides help methods for manipulation with float numbers. The following float formats defined by IEEE 754 standard are supported: - half precision float point format (https://en.wikipedia.org/wiki/Half-precision_floating-point_format) - single precision float point format (https://en.wikipedia.org/wiki/Single-precision_floating-point_format) - double precision float point format (https://en.wikipedia.org/wiki/Double-precision_floating-point_format)
