Order of operations

Each calculation is performed in the following order of precedence :
1) Expression inside parentheses.
2) Coordinates transformation, and Type B functions which are
required pressing the function key before entering, for example,
sin, cos, tan, sin
cosh
, tanh
–1
3) Type A functions which are required entering values before
pressing the function key, for example, X
r, g.
4) Exponentiation ( ^ ),
5) Fractions
6) Abbreviated multiplication format in front of variables, π, RAND.
7) ( – )
8) Abbreviated multiplication format in front of Type B functions
2√3, Alog2, etc.
9) nPr, nCr
10) x , ÷
11) +, –
12) AND, NAND
13) OR, XOR, XNOR
14) Conversion (A
• When functions with the same priority are used in series,
execution is performed from right to left.
otherwise, execution is from left to right.
• Compound functions are executed from right to left.
• Anything contained within parentheses receives the highest
priority.

Accuracy and Capacity

Output accuracy : ± 10th digit
Internal digits : SRP-280 → 24 digits
SRP-285 → 14 digits
In general, every reasonable calculation is displayed up to 10 digits mantissa,
or 10-digits mantissa plus 2-digits exponent up to 10
Numbers used as input must be within the range of the given function as follow
:
