── DECIMAL ── ( ──<string expression>── ) ─────────────────────────────┤

The DECIMAL function returns the double-precision value represented by the string expression. The string expression must yield a valid number on evaluation. For more information on the <number> construct, see Language Components.For example, the assignment D := DECIMAL(STR); is valid for the following strings:

STR = "+5497823"
STR = "1.75@-46" 
STR = "-4.31468"
STR = "@2"
STR = "+549"!!"7823" 

However, the program receives a run-time error for the following strings:

STR = "50 00."
STR = "1,505,278,00"
STR = "1@2.5"
STR = ".573"!!"5.82"
