.SH DESCRIPTION
This engine is a general-purpose calculator. The calculator operates on floating-point values and 3D floating-point vectors. The engine takes up to eight inputs of each type (\*(CbSoMFFloat\f1 and \*(CbSoMFVec3f\f1), and produces up to four
\&outputs of each type. 
.sp
Each input field (\*(Cba\f1-\*(Cbh\f1, \*(CbA\f1-\*(CbH\f1) can have multiple values, allowing the engine to evaluate the expression with different values in parallel. Some inputs may have more values than others.
\&In such cases, the last value of the shorter inputs will be repeated as necessary. 
.sp
The \*(Cbexpression\f1 input string specifies the expression to be evaluated. An expression can consist of multiple subexpressions. Several
\&subexpressions can be specified in one string, separated by semicolons (;). Alternatively, the subexpressions can be stored in separate strings in the multiple-valued input field. 
.sp
Each subexpression is
\&of the form: 
.nf
.in 1i

<lhs> = <rhs>

.fi
.in 0.5i
The \*(Cr<lhs>\f1 can be any one of the outputs or a temporary variable. The engine provides 8 temporary floating-point variables (ta, tb, tc, td, te, tf, tg, and th), and 8 temporary vector variables
\&(tA, tB, tC, tD, tE, tF, tG, and tH). You can assign a value to one component of a vector output (\*(CbA\f1-\*(CbH\f1) or a vector variable (\*(CbtA\f1-\*(CbtH\f1) by using the [\|] operator. For example, oA[0] = <rhs>, will evaluate the right
\&hand side and assign the value to the first component of the output vector \*(CboA\f1. 
.sp
The \*(Cr<rhs>\f1 supports arithmetic, logical and conditional operators. They are: 
.nf
.in 1i

(unary)   !, -
(binary)  +, -, *, /, %, <, > <=, >=, ==, !=, &&, ||
(ternary) ? : 

.fi
.in 0.5i
The ternary operator is a conditional operator. For
\&example, \*(Cra ? b : c\f1 evaluates to b if a != 0, and to c if a==0. 
.sp
Valid operands for the \*(Cr<rhs>\f1 include the inputs, outputs, temporary variables, and their components (e.g. oA[0]). Operands can also be numeric constants
\&(e.g. 1.0), pre-defined named constants, or pre-defined functions. 
.sp
The named constants are: 
.nf
.in 1i

MAXFLOAT 
MINFLOAT  
M_E 
M_LOG2E 
M_LOG10E 
M_LN2 
M_LN10 
M_PI 
M_SQRT2  = sqrt(2)
M_SQRT1_2 = sqrt(1/2)

.fi
.in 0.5i
Most of the pre-defined functions come from the math library: 
.nf
.in 1i

cos, sin, tan, 
acos, asin, atan, atan2, 
cosh, sinh, tanh,
sqrt, pow, exp, log, log10,
ceil, floor, fabs, fmod. 

.fi
.in 0.5i
Other functions are defined by \*(CbSoCalculator\f1. They are: 
.nf
.in 1i

rand(f) - Random number generator
cross(v1, v2) - Vector cross product 
dot(v1, v2) - Vector dot product 
length(v) - Vector length
normalize(v) - Normalize vector
vec3f(f1, f2, f3) - Generate a vector from 3 floats

.fi
.in 0.5i
The
\&subexpressions are evaluated in order, so a variable set in the <lhs> of an earlier expression may be used in the <rhs> of a later expression. 
.sp
Note, when the input has multiple values, all the subexpressions
\&specified in the \*(Cbexpression\f1 are applied to all the multiple input values. This is unlike the \*(CbSoBoolOperation\f1 engine, where each operation is applied only to the corresponding entries of the input data. Note also, that even though
\&the inputs and outputs can have multiple values the [\|] operator is only for indexing into the values of a single vector. It does not index into the multiple values of a field. For example, if the floating-point
\&input field \*(Cba\f1 has two values: 1.0, and 2.0, then the expression 
.nf
.in 1i

"oA[0]=a; oA[1]=a; oA[2]=0.0"

.fi
.in 0.5i
will produce two output vectors in \*(CboA\f1: (1.0, 1.0, 0.0) and (2.0, 2.0, 0.0). 
.sp
Examples of expressions: 
.nf
.in 1i

"ta = oA[0]*floor(a)"
"tb = (a+b)*sin(M_PI)"
