Synopsis

isfloat ( arg anything );
 

Description

isfloat returns one if its argument is of type single float, zero otherwise.

isfloat(0.0)  		-> 0 (No it is not, because decimal
				literals are by default
				converted to double precision
				numbers)
isfloat(atof('0.0'))	-> 1 (Only with explicit atof we get
				a single float)
