 Differs from [modulo](#modulo) in that it returns zero when the divisor is zero.
 
-## positive_modulo(a, b)
-Calculates the remainder when dividing `a` by `b`. Similar to function `modulo` except that `positive_modulo` always return non-negative number.
+## positiveModulo(a, b), positive_modulo(a, b), pmod(a, b)
+Calculates the remainder when dividing `a` by `b`. Similar to the function `modulo` except that `positive_modulo` always returns a non-negative number.
 
-Notice that `positive_modulo` is 4-5 times slower than `modulo`. You should not use `positive_modulo` unless you want to get positive result and don't care about performance too much.
