Table 9.19(a) Functions That Can be Used with the Calculation Key
Function
name
Type Explanation
SIN Real Sine (degrees)
COS Real Cosine (degrees)
TAN Real Tangent (degrees)
ASIN Real Arcsine
ACOS Real Arccosine
ATAN Real Arctangent
SQRT Real Square root
ABS Real Absolute value
LN Real Natural logarithms
EXP Real Exponent with base e (= 2.718...)
- Description of the arguments of function atan
Function atan must be described as follows:
ATAN[expression-1]/[expression-2]
X= expression-2
Y= expression-1
(Examples)
ATAN[0]/[1] -> .0
ATAN[1]/[0] -> 90.0
ATAN[1]/[1] -> 45.0
ATAN[-1]/[-1] -> -135.0
- Priority of operations
(1) Function > multiplication > addition
(2) Brackets [ ] can be used to change the priority of operations.
(Example) SIN[[[10+15]*0.1+0.5]*10]

Priority of operations
- Operation precision
The operation precision for the real type is the same as that for custom
macro operation commands.
