Bin$ Function ✔ Appearance ✔ Standard ✔ Console Syntax binString$ = bin$( expr ) Description This function returns a string of zeros and ones representing the binary value of expr, in "two's-complement integer" format (this is the native format in which integers are stored in FB). If defstr byte is in effect, an 8-character string will be returned. If defstr word is in effect, a 16-character string will be returned. If defstr long is in effect, a 32-character string will be returned. Example The chart below shows the results of bin$ on some integer values. (If a non-integer expr is used, bin$ converts it to an integer before generating the string.) The chart assumes that defstr word is in effect. The chart below shows the results of bin$ on some integer values. (If a non-integer expr is used, bin$ converts it to an integer before generating the string.)

Byte variables can handle a binaryString$ up to 8 characters in length; short-integer variables can handle a binaryString$ up to 16 characters in length; long-integer variable can handle a binaryString$ up to 32 characters in length.
