How to check if variable is Integer
FoxPro doesn't provide a direct way to check if variable is integer or how many digits it has after decimal point but it can be accomplished using PADL() function.
$SAMPLECODE$
1 2 3 4 5 6 7 8 9 10 11 lnValue = 1.000 * Is Variable integer? ? NOT ( SET("Point") $ PADL(lnValue,20) ) && Is whole number? ? (lnValue % 1) = 0 * How many digits after decimal point? ? -AT(SET("Point"), PADL(m.lnNumber,20)) % 20
