NAME

SYNOPSIS

DESCRIPTION

except that the handling of errors may differ.
If the value cannot be represented, the behaviour is undefined.

RETURN VALUE

The
atof()
function returns the converted value if the value can be
represented.

ERRORS

No errors are defined.

EXAMPLES

None.

APPLICATION USAGE

The
atof()
function is subsumed by
strtod()
but is retained because it is used extensively in existing code. If the number
is not known to be in range,
strtod()
should be used because
atof()
is not required to perform any error checking.
