operator-()

Tickstamp SRL::Tickstamp::operator- ( const Tickstamp & other ) const

inlinenoexcept

64-bit subtraction with borrow (hardware-accelerated).

Parameters

other

Tickstamp to subtract from this one (this - other)

Returns

New Tickstamp containing the difference

Performs atomic 64-bit subtraction using inline SH-2 assembly (subc). The operation handles overflow/borrow correctly across the 64-bit range.

Operation:

result = this - other;  // 64-bit subtraction with carry/borrow

Example:

Tickstamp later = Timer::Capture();
Tickstamp earlier = Timer::Capture();
Tickstamp diff = later - earlier;  // Time elapsed between captures

Note

This is the primary method for calculating time deltas. The result maintains full 48-bit precision for subsequent conversion.
