Format for Numbers
Operators
Priority Rules and Brackets
●
Upper and lower cases can be used arbitrarily.
●
An expression may include any number of spaces at any position. The
spaces will be ignored.
To the format of numbers, the following applies:
●
As decimal separator both, the point and the comma can be used.
●
Leading zeros in front of the decimal separator can be omitted (e.g. -.
668 instead of -0.668).
●
A positive sign can generally be omitted. A negative sign must be written
whereas here, brackets around the negative figure - as it is usual as op‐
posed to arithmetic - can be omitted (e.g. -3.2*-4 instead of
(-3.2)*(-4), SIN-30 instead of SIN(-30)). It must, however, gener‐
ally be noted in the single case that the operators for addition and sub‐
traction are identical with the signs and that the operators must generally
be maintained.
●
Numbers can also be written down in exponential notation. The mantissa
is to be followed by an "E" or an "e" introducing the exponent. The mantissa
may contain a decimal separator. The exponent must be integer and must
not include a decimal separator (examples: -13.783E-10, .55e+4 and
2.345E12).
The following operators can be used in expressions:
●
Addition: +,
●
Subtraction: -,
●
Multiplication: *,
●
Division: / and
●
Power: ^.
●
The operator for the multiplication can be omitted in front of
function names, in front of constants and after brackets (e.g.
5(3.4-66) instead of 5*(3.4-66), (3120+750).5 in‐
stead of (3120+750)*.5, -50SIN30 instead of
-50*SIN30). The asterisk must, however, not be omitted if it
is followed by a sign (e.g. (22-1.5)*-30 must not be sim‐
plified and become (22-1.5)-30.
●
For roots
rocal radicand as exponent x^(1/n). For the square root, you
can also use the "SQRT" function.
The interpretation of the expressions complies with the priority rules for oper‐
ators. The order of the calculation applies (with decreasing priority):
1.
Function call (with succeeding argument),
2.
Power
3.
Multiplication and division as well as
4.
Addition and subtraction.
Operations with operators equal with regard to the order are calculated in the
order from left to right.
If for the calculation, an order deviating from these rules is to be used, brackets
must be set around the preferred part of the expression. In this connection, only
round brackets are admissible. You can use as many brackets as you want and
open as many brackets within one expression as you want, however always in
