示例1: numberParser
export function numberParser(notation: string) {
let bigNum: BigNumber;
if (!numberMatcher.test(notation)) {
bigNum = new BigNumber(NaN);
}
else if (/[eE]/.test(notation)) {
const [base, power] = notation.split(/[eE]/);
bigNum = new BigNumber(base).multipliedBy(Math.pow(10, Number(power)));
}
else if (/[puμnmkMG]$/.test(notation)) {
const base = notation.substring(0, notation.length - 1);
const rankOri = notation[notation.length - 1];
const rank = rankOri === 'u' ? 'μ' : rankOri;
const power = RankEnum[rank];
bigNum = new BigNumber(base).multipliedBy(Math.pow(10, power));
}
else {
bigNum = new BigNumber(notation);
}
return bigNum.toNumber();
}示例2: BigNumber
const y = new BigNumber(235.4325)
const z = new BigNumber('0.0098074')
// Serialize an array of three BigNumbers
const str = JSON.stringify([x, y, z])
// "["1.777e+459","235.4325","0.0098074"]"
// Return an array of three BigNumbers
JSON.parse(str, function (key, val) {
return key === '' ? val : new BigNumber(val)
})
}
{
const x = new BigNumber(456.789)
x.toNumber() // 456.789
const y = new BigNumber('45987349857634085409857349856430985')
y.toNumber() // 4.598734985763409e+34
const z = new BigNumber(-0)
1 / +z // Infinity
1 / z.toNumber() // -Infinity
}
{
Math.pow(0.7, 2) // 0.48999999999999994
const x = new BigNumber(0.7)
x.toPower(2) // '0.49'
new BigNumber(3).pow(-2) // '0.11111111111111111111'
