Evaluates one or more string expressions using an increased memory size for arithmetic operations. This improves the accuracy of floating point calculations. For more details, see this video explanation: https://www.youtube.com/watch?v=g7A8OFi1mdU.
The expression(s) must be passed as strings, to avoid large numbers being converted to normal cfml numbers (which have limits on there precision) before they are evaluated.
This function takes zero or more dynamic arguments. See examples for details.
You can see in the examples that use of PrecisionEvaluate() uses a 'string'. Despite using the PrecisionEvaluate function, if you omit the quotes, Lucee will perform "normal" math on the arguments, supplied.
dump( ( 59+10.99 ) * 100 ); // 6998.999999999999 dump( PrecisionEvaluate( "( 59+10.99 ) * 100" ) ); // 6999
