Frontier	Stop and Arithmetic Operations

Index 1 is top of the stack. See PUSH.

Notes

All values are treated as two’s complement signed 256-bit integers. Note the overflow semantic when −2²⁵⁵ is negated.

Stack input

0. a: integer numerator.
1. b: integer denominator.

Stack output

0. a // b: integer result of the signed integer division. If the denominator is 0, the result will be 0.

Examples

*	Input	Output	*	*	Input	Output
1	10	1	*	1	0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFE	2
2	10		*	2	0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
