Codes. Conv_I8 Field
Converts the value on top of the evaluation stack to
public: static initonly System::Reflection::Emit::OpCode Conv_I8;
public static readonly System.Reflection.Emit.OpCode Conv_I8;
staticval mutable Conv_I8 : System.Reflection.Emit.OpCode

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
The stack transitional behavior, in sequential order, is:
valueis pushed onto the stack.
valueis popped from the stack and the conversion operation is attempted.
If the conversion is successful, the resulting value is pushed onto the stack.
conv.i8 opcode converts the
value on top of the stack to the type specified in the opcode, and leave that converted value on the top of the stack. Integer values of less than 4 bytes are extended to
int32 when they are loaded onto the evaluation stack (unless
conv.u is used, in which case the result is also
native int). Floating-point values are converted to the
Conversion from floating-point numbers to integer values truncates the number toward zero. When converting from a
float64 to a
float32, precision can be lost. If
value is too large to fit in a
float32 (F), positive infinity (if
value is positive) or negative infinity (if
value is negative) is returned. If overflow occurs converting one integer type to another, the high order bits are truncated. If the result is smaller than an
int32, the value is sign-extended to fill the slot.
If overflow occurs converting a floating-point type to an integer the value returned is unspecified.
No exceptions are ever thrown when using this field. See Conv_Ovf_I8 and Conv_Ovf_I8_Un for equivalent instructions that will throw an exception when the result type can not properly represent the result value.
