Description

FE 01

ceq

Pushes 1 if value1 equals value2; else pushes 0.

The stack transitional behavior, in sequential order, is:

  1. value1 is pushed onto the stack.

  2. value2 is pushed onto the stack.

  3. value2 and value1 are popped from the stack; value1 is compared to value2.

  4. If value1 is equal to value2, 1 is pushed onto the stack; otherwise 0 is pushed onto the stack.

The ceq instruction compares value1 and value2. If value1 is equal to value2, then 1 (of type int32) is pushed on the stack. Otherwise 0 (of type int32) is pushed on the stack.

For floating-point number, ceq will return 0 if the numbers are unordered (either or both are NaN). The infinite values are equal to themselves.

The following Emit method overload can use the ceq opcode:

  • ILGenerator.Emit(OpCode)
