# MAXIMUM

 Syntax MAXIMUM [ ( array ) ] or MAXIMUM ( *[ value ]* ) Location Minmax (DIY Toolkit - Vol Z)

The effect of this function depends on the parameter supplied. It is however an extremely fast way of comparing values. If no parameter is supplied, then the greatest possible floating point number supported by the QL is returned - this is equivalent to 1.61585 e616.

If a single parameter is supplied which is a single dimensional floating point array, then MAXIMUM will return the value of the largest number stored within that array.

If you want to compare the values of an integer array, then use MAXIMUM% (a ‘bad parameter’ is generated with this (MAXIMUM) function).

If, however, you use the second variant to pass a list of values (either numbers or variables), then the highest value out of those parameters will be returned. Please note that you cannot pass an array in this instance - it is therefore the same as MAX.

Example

```PRINT MAXIMUM
```

Returns 1.61585e616

```DIM x(3): x(0)=10: x(1)=200: x(2)=2.5: x(3)=50.4
PRINT MAXIMUM (x)
```

Returns 200.

```PRINT MAXIMUM (100, ax ,21*10+ac)
```

Returns the highest value.

NOTE

This function cannot be compiled with Supercharge or Turbo if you intend to pass an array as the parameter.
