A simple utility to perform calculations and advanced calculations from the command-line with help from the LUA interpreter.
clc <expression>
Where <expression> is a typical LUA accepted syntax.
Specify no expression to get the version information and date.
The math namespace is also exposed to the global namespace so the following advanced commands are easily accessable.
| Function | Purpose |
|---|---|
| abs(x) | Returns the absolute value of x. |
| acos(x) | Returns the arc cosine of x (in radians). |
| asin(x) | Returns the arc sine of x (in radians). |
| atan(x) | Returns the arc tangent of x (in radians). |
| ceil(x) | Returns the smallest integer larger than or equal to x. |
| cos(x) | Returns the cosine of x (assumed to be in radians). |
| deg(x) | Returns the angle x (given in radians) in degrees. |
| exp(x) | Returns the value e power x. |
| floor(x) | Returns the largest integer smaller than or equal to x. |
| fmod(x, y) | Returns the remainder of the division of x by y that rounds the quotient towards zero. |
| huge | The value HUGE_VAL, a value larger than or equal to any other numerical value. |
| log(x) | Returns the natural logarithm of x. |
| max(x, ...) | Returns the maximum value among its arguments. |
| maxinteger | Returns the maximum value of a lua_Integer type (typically 64-bits). |
| min(x, ...) | Returns the minimum value among its arguments. |
| mininteger | Returns the minimum value of a lua_Integer type (typically 64-bits). |
| modf(x) | Returns two numbers, the integral part of x and the fractional part of x. |
| pi | The value of pi. |
| rad(x) | Returns the angle x (given in degrees) in radians. |
| random([m [, n]]) | This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. When called without arguments, returns a uniform pseudo-random real number in the range 0 to ``1. When called with an integer number m`, `random` returns a uniform pseudo-random integer in the range `1` to `m`. When called with two integer numbers `m` and `n`, `random` returns a uniform pseudo-random integer in the range `m` to `n`. |
| randomseed(x) | Sets x as the seed for the pseudo-random generator: equal seeds produce equal sequences of numbers. |
| sin(x) | Returns the sine of x (assumed to be in radians). |
| sqrt(x) | Returns the square root of x. (You can also use the expression x^0.5 to compute this value.) |
| tan(x) | Returns the tangent of x (assumed to be in radians). |
