Numeric functions

abs Function

Returns the absolute value of its argument.

Synopsis

%result = abs(value)

Parameters

Returns

• If value is a positive number or 0, returns value.

• If value is a negative number, returns the absolute value of value, i.e. with the negative sign removed.

• If value is a string, returns 0.

bool function

Converts a value into the number 0 or 1.

Synopsis

%bool_value = bool(%some_value)

Parameters

Returns

• If value is an empty string or the number 0 or a string represents the numeric value 0, returns 0.

• Otherwise, returns 1.

integer function

Converts a value into a number.

Synopsis

%num = integer(%string_variable)

Parameters

Returns

• If value is a number, returns number.

• If value is a string which can be interpreted as a number, it returns number converted to a number.

• Otherwise, returns 0.

min, max functions

Returns the smallest (min) or largest (max) value from its parameter list.

Synopsis

%smallest = min(value1, value2, ...)
%largest = max(value1, value2, ...)

Parameters

Both functions require at least one parameter; and number of additional parameters is allowed. Parameter values which cannot be converted into a number are replaced by the number 0.

Returns

• min returns the smallest value of all its parameters.

• max returns the largest value of all its parameters.

pow function

Calculates the power of a number.

Synopsis

%result = pow(2, 3) // returns 8

Parameters

Returns

The base, taken to the exponent-th power, rounded towards zero to the nearest integer.

Behaviour is undefined in case of arithmetic overflow.

random function

Generates a random number within the specified limits.

Synopsis

%rnd = random(10, 20)

Parameters

Returns

A number randomly chosen between minimum and maximum (including both limits).

Numbers are evenly distributed in the interval, but sequential correlations may exist.
