nanf

Description:

public float nanf (string tagb)

Returns a representation (determined by tag) of a quiet float.NAN.

Note:

Remember to link the math library: valac -X -lm ...

If the implementation does not support quiet float.NANs, the function returns zero.

The argument tag is used in an unspecified manner. On IEEE 754 systems, there are many representations of float.NAN, and tag selects one. On other systems it may do nothing.

Parameters:

tag

A representation tag.
