When extracting the integer part, the result may be incorrect as a decimal number due to floating point errors. e.g. 0.285 * 10000000000 => 2849999999.9999995 floor(0.285 * 10000000000) => 2849999999
Add 1 to the absolute value of the value adjusted by floor or ceil, use the exponent to return it to its original precision, and compare it with value. If it is equal to value, it is assumed that the absolute value is 1 smaller due to error and will be corrected. e.g. 0.285 * 10000000000 => 2849999999.9999995 floor(0.285 * 10000000000) => 2849999999 (tmp_value) tmp_value2 = 2849999999 + 1 => 2850000000 2850000000 / 10000000000 == 0.285 => true tmp_value = tmp_value2
