fGoIfWLTQ LLLL [D>=23]

PC = (W < Q) ? LLLL : (PC + 1)

"Go if W less than Q"

Compares the contents of the floating point registers W and Q. Transfers program control (jumps) to the destination LLLL if is less than Q. Does not affect the contents of W or Q.

Dialect restriction: This instruction is not implemented in boards with dialect numbers less than 23.

Example:

	fAnin		TempSensor		;Read the temperature sensor
  	fRecallQ	SetPoint		;Get the current set point
  	fGoIfWLTQ	TurnOnHeater	;Jump if the temperature is too low

Note that there is an inherent hazard in comparing two floating point numbers for equality. The numbers you are comparing may have been arrived at via a number of arithmetic operations. Because floating point arithmetic has limited accuracy (24 bits = about 6 or 7 decimal digits in our case), two numbers that should be identical may differ by a small amount. That means an equals test may fail on two numbers that should be identical.
