== Description: ==
Evaluate arithmetic floating point expressions written in C and Bison for
parser and Flex for scanner. This library is oriented to work with Bash.
Evaluate each ARG as an arithmetic expression. Each expression ends with
semicolumn. The following list of operators is grouped into levels of
equal-precedence operators. The levels are listed in order of decreasing
precedence.
id++, id-- variable post-increment, post-decrement
++id, --id variable pre-increment, pre-decrement
-, + unary minus, plus
!, ~ logical and bitwise negation
** exponentiation
*, /, % multiplication, division, remainder
+, - addition, subtraction
<<, >> left and right bitwise shifts
<=, >=, <, > comparison
==, != equality, inequality
& bitwise AND
^ bitwise XOR
| bitwise OR
&& logical AND
|| logical OR
boolean_exp ? scalar_exp : scalar_exp conditional operator
=, *=, /=, %=,
+=, -=, <<=, >>=,
&=, ^=, |= assignment
id=scalar_exp|boolean_exp
acos(scalar_exp) computes arc cosine.
acosh(scalar_exp) computes arc hyperbolic cosine.
asin(scalar_exp) computes arc sine.
asinh(scalar_exp) computes the hyperbolic of arc sine of an argument.

atan2(scalar_exp) computes the arc tangent of an argument.
atanh(scalar_exp) computes arc hyperbolic tangent.
cbrt(scalar_exp) computes cube root of a number.
ceil(scalar_exp) computes the nearest integer greater than argument.
cos(scalar_exp) computes the cosine of an argument.
cosh(scalar_exp) computer hyperbolic cosine.
exp(scalar_exp) computes the exponential raised to the argument.
fabs(scalar_exp) computes absolute value.
floor(scalar_exp) calculates the nearest integer less than argument.
hypot(scalar_exp) computes hypotenuse.
log(scalar_exp) computes natural logarithm of an argument.
log10(scalar_exp) computes the base 10 logarithm of an argument.
pow(scalar_exp) Computes power of a number.

sqrt(scalar_exp) computes square root of a number.
tan(scalar_exp) computes tangent.
tanh(scalar_exp) computes the hyperbolic tangent of an argument.
