Method Details

evaluateUnary

long evaluateUnary(int sizeout,
 int sizein,
 long unsignedIn1)

Evaluate the unary operation using long data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed long value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

unsignedIn1 - unsigned input 1

Returns:

operation result.

• Utils.bytesToLong(byte[], int, boolean)

evaluateUnary

BigInteger evaluateUnary(int sizeout,
 int sizein,
 BigInteger unsignedIn1)

Evaluate the unary operation using BigInteger data

NOTE: if the operation overflows bits may be set beyond the specified sizeout. Even though results should be treated as unsigned it may be returned as a signed value. It is expected that the returned result always be properly truncated by the caller since the evaluation may not - this is done to conserve emulation cycles.

Parameters:

sizeout - intended output size (bytes)

sizein - in1 size (bytes)

unsignedIn1 - unsigned input 1

Returns:

operation result.
