ee.Number.float
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
將輸入值轉換為 32 位元浮點數。
範例
程式碼編輯器 (JavaScript)
// Declare an ee.Number.
var number = ee.Number(100);
print('ee.Number:', number);
// Cast a number to signed 32-bit floating point.
var floatNumber = number.float();
print('ee.Number cast to float:', floatNumber);
Python 設定

Python 環境頁面，瞭解 Python API 和如何使用 geemap 進行互動式開發。
import ee
import geemap.core as geemap
Colab (Python)
# Declare an ee.Number.
number = ee.Number(100)
print('ee.Number:', number.getInfo())
# Cast a number to signed 32-bit floating point.
float_number = number.float()
print('ee.Number cast to float:', float_number.getInfo())
