Numeric Calculations

ipow - Integer Power Function

ipow( base = arg exp = n ), equivale a: arg ** n , pero ipow tiene mejor performance, ejemplo programa DEMO_IPOW

nmax, nmin - Numeric Extremum Functions

Syntax Forms

... nmax|nmin( val1 = arg1 val2 = arg2 [val3 = arg3] ... [val9 = arg9] ) ...

Effect

These functions return the value of the greatest or the least of the arguments passed. A minimum of two arguments, arg1 and arg2, and a maximum of nine arguments must be passed. Here, the optional input parameters val3 to val9 must be filled in ascending order without gaps. The arguments arg1 to arg9 are numeric expression positions.
