# This module is used by the optimizer for resolving constant values.
# The functions it implements are all functions that always return the same result when given the same input, and that have no side effects.
# For example, llAbs() is here, but llFrand() is not, because it doesn't always return the same result.
# This implies that functions present in this module can be precomputed if their arguments are constants.

# In some instances, the result can't be computed; in these cases the function
# raises a LSLCantCompute exception that is caught by the optimizer to leave
# the expression unchanged. For example, llBase64ToInteger("AA") returns
# unpredictable garbage in the low bytes in LSL, so it is left unchanged.
#
# The JSON functions have been separated to their own module.
