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]), type(x, double), 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], double, and hfloat are synonymous with one another.

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

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