  rel="stylesheet"
  id="bootstrap-css"

<button type="button" class="btn btn-info btn-circle btn-lg">100</button>

The above code is used from this link

You have to include the CSS for .btn-circle to have the rounded corners. I copied the CSS from the link you provided and removed all padding so the text is centered. This will result in:

.btn-circle {
  width: 30px;
  height: 30px;
  text-align: center;
  padding: 0; // changed
  font-size: 12px;
  line-height: 1.428571429;
  border-radius: 15px;
}
.btn-circle.btn-lg {
  width: 50px;
  height: 50px;
  padding: 0; // changed
  font-size: 18px;
  line-height: 1.33;
  border-radius: 25px;
}
.btn-circle.btn-xl {
  width: 70px;
  height: 70px;
  padding: 0; // changed
  font-size: 24px;
  line-height: 1.33;
  border-radius: 35px;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<button type="button" class="btn btn-info btn-circle btn-lg">100</button>

These changes will produce circular buttons with centered text:

include the .btn-circle css rules from the link you provided,
wrap the button text in a span and give the span negative margins.

body {
  padding: 1em;
}

.btn-circle {
  width: 30px;
  height: 30px;
  text-align: center;
  padding: 6px 0;
  font-size: 12px;
  line-height: 1.428571429;
  border-radius: 15px;
}

.btn-circle.btn-lg {
  width: 50px;
  height: 50px;
  padding: 10px 16px;
  font-size: 18px;
  line-height: 1.33;
  border-radius: 25px;
}

.btn-circle.btn-xl {
  width: 70px;
  height: 70px;
  padding: 10px 16px;
  font-size: 24px;
  line-height: 1.33;
  border-radius: 35px;
}


/* use negative margins to accommodate wider button text */

.btn-circle span {
  margin: 0 -2rem;
}

<link
  href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"
  rel="stylesheet"
  id="bootstrap-css"
>

<button
  type="button"
  class="btn btn-info btn-circle btn-lg"
><span>100</span></button>

A very simple class will solve your problem-

<button type="button" class="btn btn-info p-5 rounded-circle btn-lg">100</button>

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">
  <style>
    body {
  padding: 1em;
}
  </style>
  
</head>
<body>

<button type="button" class="btn btn-info p-5 rounded-circle btn-lg">100</button>

</body>
</html>
