BigFloat.prototype.toPrecision

Returns a string representation of the BigFloat in exponential notation rounded to the specifie number of digits.

Syntax

toPrecision(digits, roundingMode?, radix?)

Parameters

• digits

  The number of digits after the decimal point.

• roundingMode optional

  A rounding mode as in BigFloatEnv. Defaults to BigFloatEnv.RNDNA (Round to nearest, with ties away from zero rounding mode).

• radix optional

  The radix of the result between 2 and 36. Defaults to 10.

Return value

A string representing the value in exponential notation.
