evaluateUnary
public abstract long evaluateUnary(int sizeout, int sizein, long unsignedIn1)
Evaluate the unary operation using long data- Parameters:
sizeout
- intended output size (bytes)sizein
- in1 size (bytes)unsignedIn1
- unsigned input 1- Returns:
- operation result. 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.

evaluateUnary
public abstract java.math.BigInteger evaluateUnary(int sizeout, int sizein, java.math.BigInteger unsignedIn1)
Evaluate the unary operation using BigInteger data- Parameters:
sizeout
- intended output size (bytes)sizein
- in1 size (bytes)unsignedIn1
- unsigned input 1- Returns:
- operation result. 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.
