The type(x, sfloat) function returns true if x is a Maple software float. Otherwise, false is returned.

The type(x, float[]), type(x, float[8]), and type(x, hfloat) functions return true if x is a Maple hardware float.

The "8" in float[8] refers to the number of bytes allocated for the hardware floating-point number.  Only double precision floats (8 bytes) are currently supported. The types float[], float[8], and  are synonymous with one another.

The type(x, float) function returns true if x is of type sfloat or hfloat (or float[] or float[8]).
