Citizen SRP-145N manual Order of Operations, Accuracy and Capacity

(	: Appears when you press [ ( ]. It shows the
	present level of nesting.
( n )	: Appears when you press [SHIFT] [[X]] in the
	program learn mode and when program
	execution halts to let you enter a variable. The
	number in brackets shows the number of the
	place of the variable, and goes from 1 - 40.
	ORDER OF OPERATIONS

Each calculation is performed in the following order of precedence:

1)Functions required inputting values before pressing the function key, for example, cos, sin, tan, cos –1, sin –1, tan –1, log, ln, x 2, 1/x,

√, π, 3, x!, %, , .

2)Operation in parenthesis

3)Functions required pressing the function key before entering, for example, [ EXP ] key .

4)Fractions

ACCURACY AND CAPACITY

Functions						Input range
sin x, cos x, tan x	Deg :			x		< 1 x 10 11 deg
	Rad :			x		< 1745329252 rad
	Grad :				x	< 1.111111111 x 10 11 grad
	however, for tan x
	Deg :			x		≠ 90 (2n+1)
	Rad :			x		π
						≠ 2 (2n+1)
	Grad :
					x	≠ 100 (2n+1)
	(n is an integer)
sin –1x, cos –1x		x	≤ 1
tan –1x		x	< 1 x 10 100
sinh x, cosh x		x	≤ 230.2585092
tanh x		x	< 1 x 10 100
sinh –1x		x	< 5 x 10 99
cosh –1x	1 ≤		x < 5 x 10 99
tanh –1x		x	< 1
