Abs(a:LONG)(LONG)
Returns absolute value of <a>.
And(a:ULONG,b:ULONG)(ULONG)
Returns <a>&.

BitCount(value:ULONG)(LONG)
Returns # of bits contained in 32bit <value>.

  BitCount($0f0) returns 4 : $0f0=%0000.1111.0000
  BitCount($124) returns 3 : $124=%0001.0010.0100

BitSize(value:ULONG)(LONG)
This returns size of bit field contained in the 32bit <value>

  BitSize($2c) returns 4  : $2c=%0010.1100
            size is this  :        ^^ ^^
  BitSize(5) returns 3    : 5=%101
            size is this  :    ^^^
  BitSize($124) returns 7 : $124=%0001.0010.0100
            size is this  :          ^ ^^^^ ^^
  BitSize(a) equals to HiBit(a)-LoBit(a)

Bounds(a:LONG,min:LONG,max:LONG)(LONG)
Bounds <a> with <min> and <max> and returns the result. It is the same as:
```
 res:=IF a<min THEN min ELSE IF a>max THEN max ELSE a
```
EOr(a:ULONG,b:ULONG)(ULONG)
Returns <a>!.
Even(a:LONG)(BOOL)
Returns -1 if <a> is even else 0.
F2I(a:DOUBLE)(LONG)
Converts the float/double <a> to LONG with rounding.
HiBit(value:ULONG)(LONG)
This returns position of highest active bit of the 32bit <value>
InBounds(min:LONG,val:LONG,max:LONG)(BOOL)
Compares the value with min and max, and returns TRUE if the value fits to the bounds. It's the same as:
```
 res:=IF min<=val<=max THEN TRUE ELSE FALSE
```
LoBit(value:ULONG)(LONG)
This returns position of lowest active bit of the 32bit <value>
Max(a:LONG,b:LONG)(LONG)
Returns the bigger value of <a> and .
Min(a:LONG,b:LONG)(LONG)
Returns the smaller value of <a> and .
Neg(a:LONG)(LONG)
Returns negated <a>.
Not(a:ULONG)(ULONG)
Returns noted <a>.
Odd(a:LONG)(BOOL)
Returns -1 if <a> is odd else 0.
Or(a:ULONG,b:ULONG)(ULONG)
Returns <a>|.
Pow(a:DOUBLE,b:DOUBLE)(DOUBLE)
Returns <a>^. If =0, 1 is returned.
Rol(a:ULONG,b:LONG)(ULONG)
Returns <a> rotated left by bits.
Ror(a:ULONG,b:LONG)(ULONG)
Returns <a> rotated right by bits.
Shl(a:ULONG,b:LONG)(ULONG)
Returns <a> shifted left by bits.
Shr(a:ULONG,b:LONG)(ULONG)
Returns <a> shifted right by bits.
Sign(a:LONG)(LONG)
Returns 1 if <a>>0 or -1 if <a><0, else 0.
