• Constructor Detail

• FloatCRTMath

Creates a carry-CRT math using the specified radix.
Parameters:
radix - The radix that will be used.
• Method Detail

• multiply

public final void multiply​(float[] src,
float factor,
float[] dst)
Multiplies two words by one word to produce a result of three words. Most significant word is stored first.
Parameters:
src - Source array, first multiplicand.
factor - Second multiplicand.
dst - Destination array.
• compare

public final float compare​(float[] src1,
float[] src2)
Compares three words. Most significant word is stored first.
Parameters:
src1 - First operand.
src2 - Second operand.
Returns:
Less than zero if src1 < src2, greater than zero if src1 > src2 and zero if src1 == src2.

public final float add​(float[] src,
float[] srcDst)
Adds three words. Most significant word is stored first.
Parameters:
src - First operand.
srcDst - Second operand, and destination of the operation.
Returns:
Overflow carry bit.
• subtract

public final void subtract​(float[] src,
float[] srcDst)
Subtracts three words. Most significant word is stored first.
Parameters:
src - First operand.
srcDst - Second operand, and destination of the operation.
• divide

public final float divide​(float[] srcDst)
Divides three words by the base to produce two words. Most significant word is stored first.
Parameters:
srcDst - Source and destination of the operation.
Returns:
Remainder of the division.
