Another GW-BASIC tip: Copyright 1990 Tony B. Anderson, All Rights Reserved If you're attempting to convert Model 100 family BASIC programs to run under GW-BASIC, and find cases of Integer division in the Model 100 programs expressed by the backslash character "\" (GRPH-hyphen), you should be aware that it doesn't work exactly the same as it does in Model 100 BASIC. For purposes of illustration, let's use the example: A = 7.5\4 or A = X\Y In Model 100 BASIC, this returns an integer in A, which is equal to "how many times will 4 go into 7.5 evenly, or Y into X, disregarding any leftover". In GW-BASIC, Both values are rounded UP or DOWN to the nearest integer first, THEN the division is made. In the case of the above example, 7.5 would be rounded UP to the whole number 8, then the formula becomes: A = 8\4 which sets A to a value of 2. If 7.5 were 7.4, then it is rounded DOWN to the whole number 7, which sets the value of A to 1. Likewise, if the number 4 were 4.3, it would be rounded down to 4.0, and if it were 4.5 or greater, it would be rounded up to 5.0, causing other division problems. This might cause some problems in calculations, in getting accurate results in programs which are converted from Model 100 BASIC to GW-BASIC. Converting such statements to the equivalent A = INT(7.5/4) or A = INT(X/Y) provides the expected result.
