Method SingleToSByte

SingleToSByte(Single, Int32, Int32)

Converts a 32 bit to an 8 bit .

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.

NOTE: This was floatToByte() in Lucene

Declaration
public static sbyte SingleToSByte(float f, int numMantissaBits, int zeroExp)
Parameters
Type Name Description
System.Single f

System.Int32 numMantissaBits

The number of mantissa bits to use in the byte, with the remainder to be used in the exponent.

System.Int32 zeroExp

The zero-point in the range of exponent values.

Returns
Type Description
System.SByte
