convertToExpMantissa Method

convertToExpMantissa(float)

Converts the floating point value to its exponent-mantissa representation. The mantissa occupies the 11 least significant bits (bits 10-0), and the exponent the previous 5 bits (bits 15-11).

Declaration

public static int convertToExpMantissa(float step)

Parameters

Type	Name	Description
float	step	The quantization step, normalized to a dynamic range of 1.

Returns

Type	Description
int	The exponent mantissa representation of the step.
