arithmetic operators
•
pre-defined functions
The following binary arithmetic operators are supported:
+
:
addition
-
:
subtraction
*
:
multiplication
/
:
division
%
:
remainder
^
:
exponentiation (raise to power)
Variables and numeric values can be used and parentheses () can also be used to any level of nesting. Expressions
can be sequenced and separated by semicolons, with intermediate variables used. Variable names are alphanumeric
strings and are not case-sensitive. White space (blank, tab, new line, etc) has no significance.
The following pre-defined functions are supported. These words are reserved and cannot be used as variable names:
abs(n)
-
absolute value of n
acos(x)
-
arc cosine of x, in radians
asin(x)
-
arc sine of x, in radian
atan(x)
-
arc tangent of x, in radians
ceil(x)
-
smallest integer >= x
cos(x)
-
cosine of x (x in radians)
cosh(x)
-
hyperbolic cosine of x (x in radians)
E10(x)
-
10 raised to the power x
exp(x)
-
exponential function of x
floor(x)
-
largest integer <= x
log10(x)
-
base-10 logarithm of x
log(x)
-
natural logarithm of x
sin(x)
-
sine of x (x in radians)
sinh(x)
-
hyperbolic sine of x
sqrt(x)
-
square root of x
tan(h)
-
tangent of x (x in radians)
tanh(h)
-
hyperbolic tangent of x (x in radians)
j0(x)
-
bessel function of first kind, order 0
j1(x)
-
bessel function of first kind, order 1
y0(x)
-
bessel function of second kind, order 0
y1(x)
-
bessel function of second kind, order 1
max(x1,x2)
-
larger of x1 and x2
min(x1,x2)
-
smaller of x1 and x2
Function arguments must be enclosed in parentheses.
e.g. sin(y), not siny or sin y.
The function names are not case-sensitive. There are no user-defined functions as yet.
Examples:
2.5*a^2/b + 1.2*c^2/sin(d)
