regex - 正则表达式匹配带和不带逗号的数字和小数

Question

即使有逗号和小数，我也想匹配数字/小数。例如，我希望它能够匹配一个句子。数字可以在句子的中间、开头或结尾：

the number is 1000 today
the number is 1000.00 today
the number is 1000.142 today
the number is 1000.30 today
the number is 1000.200 today
the number is 1,000 today
the number is 1,000.00 today
the number is 1,000.142 today
the number is 1,000.30 today
the number is 1,000.200 today

我已经尝试过^\d*\.?\d+$，但似乎没有工作
