Value functions in NTGML

typeof(value)➜

Returns the type of a value as a string.

This is slower than calling the respective is_ function or two.

is_number(value)➜

Same as is_numeric.

is_real(value)➜

is_numeric(val)➜

is_string(val)➜

is_undefined(val)➜

is_int32(val)➜

is_int64(val)➜

is_bool(val)➜

is_infinity(val)➜

is_struct(val)➜

is_method(val)➜

is_array(val)➜

is_callable(val)➜

is_handle(val)➜

And the following are extra:

is_object(val)➜

Returns whether a value is a struct, but not a wrapper for a data structure/etc.

is_builtin(val)➜

Returns whether a value is a wrapper for a data structure/etc. and not a struct.

is_double(val)➜

In "legacy" NTGML, is_real is an alias for is_numeric and this is the actual is_real.

string(value_or_template, ...values)➜

int64(value)➜

And the following are extra:

string_is_real(str)➜

Returns whether a string contains a valid number (signed, fractional, no exponents/infinities).

string_to_real(str, default_value = 0)➜

Converts a string to a number if it's valid (rules per above) or returns default_value if it isn't.

In "legacy" NTGML, real(str) is equivalent to string_to_real(str, 0) for backwards compatibility.
