float firtex::utility::CSmallFloat::byteToFloat (  byte  b, int  numMantissaBits, int  zeroExp )  [inline, static]

Converts an 8 bit float to a 32 bit float.

byte firtex::utility::CSmallFloat::floatToByte (  float  f, int  numMantissaBits, int  zeroExp )  [inline, static]

Converts a 32 bit float to an 8 bit float. Values less than zero are all mapped to zero. Values are truncated (rounded down) to the nearest 8 bit value. Values between zero and the smallest representable value are rounded up. 参数: f  the 32 bit float to be converted to an 8 bit float (byte) numMantissaBits  the number of mantissa bits to use in the byte, with the remainder to be used in the exponent zeroExp  the zero-point in the range of exponent values 返回: the 8 bit float representation
