`float`tofloat(`value`)- Converts (almost) any MOO value into a floating point number.
`float`floor(`float`)- Rounds the argument towards negative infinity and returns the result.
`float`ceil(`float`)- Rounds the argument towards positive infinity and returns the result.
`list`frexp(`float`)- Splits the argument (
`x`) into a fraction`f`and an integer exponent`n`, such that either`f == 0.0`, or`0.5 <= | f | < 1.0`and`f * 2 ** n == x`.`{`is returned. If the argument equals 0.0, both`f`,`n`}`f`and`n`will be zero. `float`ldexp(`float`,`num`)- Adds an integer to the exponent of a float;
`float`* 2 **`num`is returned. This has the inverse effect of`frexp()`

. `list`modf(`float`)- Splits the argument into a fraction
`f`and an integer part`n`, such that`| f | < 1.0`, and`f + n == x`.`{`is returned. Note that`f`,`n`}`n`is returned as a float, and may not be representable as an integer.

`table`tablemap(`list`,`list`)- Creates and returns a new table built by associating each of the values
from the first argument with the corresponding elements of the second
argument. An error will result if the lists are not of the same size.
`table`tableinsert(`table`,`key`,`value`)- Returns a new table with
`{`inserted (or altered.)`key`~`value`} `table`tabledelete(`table`,`key`)- Returns a new table with the element associated with
`key`removed. `list`tablekeys(`table`)- Returns all of the keys present in the given table as a list.
`list`tablevalues(`table`)- Returns all of the values present in the given table as a list, in the
same ordering that
`tablekeys()`

returns the keys for the same table. `num`table_bound(`table`,`key`)- Returns 1 if and only if
`key`is present the given table.

`string`toliteral(`value[, usequotes]`)- Returns a string representation for
`value`, including recursive list or table elements. If`usequotes`is present and is false, string values will not be surrounded by quotation marks, and special characters within the string will not be escaped. `list`fromliteral(`string`)- Returns
`{1,`where`value`}`value`is the MOO value represented by the string argument. If the argument is malformed,`{0,`is returned instead. This function assumes that strings have been properly escaped and are surrounded by quotation marks.`reason`}

`tostr()`

- Float arguments are converted into a simple string representation. Table
arguments are converted into the string
`"{table}"`. `tonum()`

- A float argument is rounded to the nearest integer. If the float value is
so large that it cannot be represented as an integer,
`E_RANGE`will be generated. `toobj()`

- A float argument is rounded to the nearest integer, and then converted
into an object value. The same range restriction applies as for
`tonum()`

. `abs()`

- If a float argument is passed, the absolute value (also as a float) is
returned.
`sqrt()`

- If a float argument is passed, the floating point square root is
returned.
`length()`

- If a table argument is passed, the number of elements in the table is
returned.
