Cmp

Type Function: BOOL¶


Input X, Y	REAL (input)
N	INT (number of digits to be compared)
Output	BOOL (result)
	CMP compares two REAL values if the first N points are equal.

cmp

Example:

CMP(3.140,3.149,3) = TRUE   CMP(3.140,3.149,4) = FALSE CMP(0.015,0,016,1) = TRUE    CMP(0.015,0,016,2) = FALSE

In the CMP function note that the dual coding of numbers a 0.1 in the decimal system can not necessarily always displayed as 0.1 in the binary system. Rather, it may happen that represented something less than 0.1 or greater because the resolution is not the number in binary coding allows exactly one 0.1. For this reason, the function can not detect for 100% the difference of 1 in the last position. In addition, note that a data type REAL with 32 bit has only a resolution of 7 - 8 decimal places.
