%(Percent)

Type: Function

Description: Percent Function: Returns x percent of y.

Common usage is ambiguous about some units of temperature. When ºC or ºF represents a thermometer reading, then the temperature is a unit with an additive constant: 0 ºC=273.15 K, and 0 ºF=459.67 ºR. But when ºC or ºF represents a difference in thermometer readings, then the temperature is a unit with no additive constant: 1 ºC=1 K and 1 ºF=1 ºR.

The arithmetic operators +, –, %, %CH, and %T treat temperatures as differences, without any additive constant. However, +, –, %CH, and %T require both arguments to be either absolute (K and ºR), both ºC, or both ºF. No other combinations are allowed.

For more information on using temperature units with arithmetic functions, see the entry for +.

Input/Output:
		Level 2/Argument 1	Level 1/Argument 2		Level 1/Item 1
		x	y	→	xy/100
		x	'symb'	→	'%(x,symb)'
		'symb'	x	→	'%(symb,x)'
		'symb1'	'symb2'	→	'%(symb1, symb2)'
		x	y_unit	→	(xy/100)_unit
		x_unit	y	→	(xy/100)_unit
		'symb'	x_unit	→	'%(symb,x_unit)'
		x_unit	'symb'	→	'%(x_unit,symb)'
Example 1:	23.7 995 % returns 235.815.
Example 2:	15 176_kg % returns 26.4_kg.
Example 3:	100_°C 50 % returns 50_°C.
