getInstance

public static final ToFloat getInstance()

Get an instance of a ToFloat object. This avoids multiple calls to the constructor. ToFloat is thread safe.

from

public final float from(IclTerm t,
                        float def)

Convert a Term to a float primitive. If it cannot be converted, use the given default

Returns:

float: the IclTerm as a float, if possible

from

public final float from(IclTerm t)
                 throws java.lang.UnsupportedOperationException

Convert a Term to a float primitive. If it cannot be converted, throw an UnsupportedOperationException

Returns:

float: the IclTerm as a float, if possible

Throws:

java.lang.UnsupportedOperationException - if the IclTerm cannot be converted
