==== 7.5.51 imul ====

Multiply int 

Format 

imul 

Forms 

imul = 70 (0x46) 

Stack 

..., value1.word1, value1.word2, value2.word1, value2.word2 -> ..., result.word1, result.word2 

Description 

Both value1 and value2 must be of type int. The values are popped from the operand stack. The int result is value1 * value2. The result is pushed onto the operand stack. 

If an imul instruction overflows, then the result is the low-order bits of the mathematical product as an int. If overflow occurs, then the sign of the result may not be the same as the sign of the mathematical product of the two values. 

Notes 

If a virtual machine does not support the int data type, the imul instruction will not be available.
