Method Detail

getFloat

public static final float getFloat(byte[] buffer,
             int offset)

Build a Java float from a 4-byte floating point representation.

This includes DERBY types:

• REAL
• FLOAT(1<=n<=24)

Throws:

IllegalArgumentException - if the specified representation is not recognized.

getDouble

public static final double getDouble(byte[] buffer,
               int offset)

Build a Java double from an 8-byte floating point representation.

This includes DERBY types:

• FLOAT
• DOUBLE [PRECISION]

Throws:

IllegalArgumentException - if the specified representation is not recognized.

floatToIeee754Bytes

public static final void floatToIeee754Bytes(byte[] buffer,
                       int offset,
                       float f)

Write a Java float to a 4-byte floating point representation.

doubleToIeee754Bytes

public static final void doubleToIeee754Bytes(byte[] buffer,
                        int offset,
                        double d)

Write a Java double to an 8-byte double precision floating point representation.
