The JavaScript exception "precision is out of range" occurs when a number that's outside of the range of 0 and 20 (or 21) was passed into toFixed
or toPrecision
.
Message
RangeError: The number of fractional digits is out of range (Edge) RangeError: The precision is out of range (Edge) RangeError: precision {0} out of range (Firefox) RangeError: toExponential() argument must be between 0 and 20 (Chrome) RangeError: toFixed() digits argument must be between 0 and 20 (Chrome) RangeError: toPrecision() argument must be between 1 and 21 (Chrome)
Error type
Que salió mal?
Fué un argumento preciso fuera de rango en uno de estos metodos:
El rango permitido para estos metodos usualmente esta entre 0 o 20 (o 21). De todas formas la especificación ECMAScript permite extender este rango.
Method | Firefox (SpiderMonkey) | Chrome, Opera (V8) |
---|---|---|
Number.prototype.toExponential() |
0 to 100 | 0 to 20 |
Number.prototype.toFixed() |
-20 to 100 | 0 to 20 |
Number.prototype.toPrecision() |
1 to 100 | 1 to 21 |

77.1234.toExponential(-1); // RangeError
77.1234.toExponential(101); // RangeError
2.34.toFixed(-100); // RangeError
2.34.toFixed(1001); // RangeError
1234.5.toPrecision(-1); // RangeError

Casos validos
77.1234.toExponential(4); // 7.7123e+1
77.1234.toExponential(2); // 7.71e+1
2.34.toFixed(1); // 2.3
2.35.toFixed(1); // 2.4 (note that it rounds up in this case)
5.123456.toPrecision(5); // 5.1235
5.123456.toPrecision(2); // 5.1
5.123456.toPrecision(1); // 5
