Functions

clipZeros int clipZeros(BigInt n, uint digits): Trims any trailing zeros and returns the number of zeros trimmed.
countDigits int countDigits(T m): Returns the number of decimal digits in a non-negative big integer
firstDigit uint firstDigit(T n): returns the first decimal digit of the number
lastDigit int lastDigit(BigInt big): Returns the last digit of the argument.
round D round(D num): Returns the number rounded to its type precision. Flags: SUBNORMAL, CLAMPED, OVERFLOW, INEXACT, ROUNDED.
round D round(D num, Context context, bool setFlags): Rounds the number to the precision of the context parameter. if setFlags is false no context flags will be set by this operation. Returns the rounded number. Flags: SUBNORMAL, CLAMPED, OVERFLOW, INEXACT, ROUNDED.
round D round(D num, int precision, Round mode, bool setFlags): Rounds the number to the specified precision using the specified rounding mode. if setFlags is false none of the context flags will be set by this operation. Flags: SUBNORMAL, CLAMPED, OVERFLOW, INEXACT, ROUNDED.
roundStr string roundStr(string str, int precision): Returns a numeric string with the specified precision.
shiftBig BigInt shiftBig(BigInt num, int n): Decimal shift left. Shifts the number left by the specified number of decimal digits. If n == 0 the number is returned unchanged. If n < 0 the number is shifted right.
trailingZeros uint trailingZeros(BigInt n, uint digits): Returns the number of trailing zeros in the argument.
