## ˜ Lesser of

Two-argument form See also one-argument form Floor

Finds the smaller of two numbers. Each number in the right-hand argument is compared with the corresponding number in the left-hand argument. The result is the smaller number from each comparison. (This operation is affected by ŒCT, the comparison tolerance)

           ¯9                              is considered the smaller)
