as_float(value)

Returns the value as a float

If value is a string it will be converted to a float if possible. An invalid value is returned as 0

f = as_float(4.0)      // 4.0
f = as_float(4)        // 4.0
f = as_float("4")      // 4.0
f = as_float("barb")   // 0.0
f = as_float(null)     // 0.0
f = as_float(true)     // 1.0
f = as_float([1,2,3])  // 0.0

as_int(value)

Returns the value as a int

If value is a string it will be converted to a float if possible. An invalid value is returned as 0

f = as_int(4.0)      // 4
f = as_int(4)        // 4
f = as_int("4")      // 4
f = as_int("4.0")    // 4
f = as_int("barb")   // 0
f = as_int("27th")   // 27
f = as_int(null)     // 0
f = as_int(true)     // 1
f = as_int([1,2,3])  // 0

as_string(value)

Returns the value as a string

If value is a string it will be converted to a float if possible. An invalid value is returned as null

f = as_string(4.0)      // "4.0"
f = as_string(4)        // "4"
f = as_string(null)     // null
f = as_string(true)     // "1"
f = as_string(4.0)      // "4.0"
f = as_string([1,2,3])  // null

as_point(x,y) | point(x,y)

Returns a point with x and y coordinates`

local p = point(10,20)

as_point has the added benifit of being able to convert a string to a point

local p = as_point("{100, 200}")

If the string is an invalid point, point(0,0) will be returned.

is_table(value)

Returns true if value is a table

is_array(value)

Returns true if value is a array

is_string(value)

Returns true if value is a string

is_int(value)

Returns true if value is a int

n = is_int(4)    // true
n = is_int(4.0)  // false

is_float(value)

Returns true if value is a table

n = is_int(4)    // false
n = is_int(4.0)  // true

is_point(value)

Returns true if value is a point

p = point(100,100)
n = is_point(p)    // true

is_number(value)

Returns true if value is a float or int

n = is_number(4)    // true
n = is_number(4.0)  // true
n = is_number("4")  // false
n = is_number(null) // false

is_function(value) | is_function(value, param_count)

Returns true if value is a function and takes param_count parameters (if supplied).

f = function() { return 10 }
n = is_function(f)      // true
n = is_function(null)   // false
n = is_function(f())    // false

g = function(foo) { return foo+1 }
n = is_function(g,1)    // true
n = is_function(g,0)    // false

h = function(foo=0) { return foo+1 }
n = is_function(h,1)    // true
n = is_function(h,0)    // true
