ee.Number.int8

  • Number.int8() casts a number to a signed 8-bit integer with a range of [-128, 127].

  • Casting floating-point numbers to int8 results in the loss of decimal precision.

  • Numbers outside the int8 range [-128, 127] will be clamped to the nearest boundary value when cast to int8.

 Casts the input value to a signed 8-bit integer.

UsageReturns
Number.int8()Number
ArgumentTypeDetails
this:inputNumberThe input value.
