Calculations with integers will not result in floating point values;
if you divide two integer values (say: ``32500 / 99``) the result will be the integer floor
division (328) rather than the floating point result (328.2828282828283). If you need the full precision,
you'll have to write ``flt(32500) / 99`` (or if they're constants, simply ``32500.0 / 99``), to make sure the
first operand is a floating point value.
you'll have to make sure at least the first operand is a floating point. So write ``32500.0 / 99.0``,
or use the type cast ``value as float``.
Arithmetic and Logical expressions
@ -542,35 +543,11 @@ len(x)
Note: this can be different from the number of *bytes* in memory if the datatype isn't a byte.
lsb(x)
Get the least significant byte of the word x.
Get the least significant byte of the word x. Equivalent to the cast "x as ubyte".
msb(x)
Get the most significant byte of the word x.
flt(x)
Explicitly convert the number x to a floating point number.
This is required if you want calculations to have floating point precision when the values aren't float already.
fintb(x)
Take floor of the floating point into a byte value. (no overflow check). Use together with b2ub() to convert into a unsigned byte instead.
fintw(x)
Take floor of the floating point into a word value. (no overflow check).
wrd(x)
Explicitly convert the value x to a signed word (sign extended).
This is required if you want calculations to have word precision when the values are different types.
uwrd(x)
Explicitly convert the byte x to an unsigned word.
This is required if you want calculations to have unsigned word precision when the values are different types.
b2ub(x)
Convert signed byte to unsinged byte. Uses 2's complement if dealing with a negative number.
ub2b(x)
Convert an unsigned byte to a signed byte. Uses 2's complement to deal with negative numbers.
any(x)
1 ('true') if any of the values in the array value x is 'true' (not zero), else 0 ('false')
