mxIsDouble returns logical 1 (true) if the mxArray stores its real and imaginary data as double-precision, floating-point numbers.
double precision类型是一种双精度浮点数类型,它占据8个字节的内存空间,可以表示的数值范围更广,精度更高。与单精度浮点数类型相比,double precision类型具有以下特点: 1. 更大的数值范围:double precision类型可以表示的数值范围更广,可以处理更大或更小的数值。这使得它在科学计算和工程设计中非常有用,可以处理极大...
例如double型的数据为a=5.1413，程序如下：incloud <stdio.h> main( ){ double a；printf("请输入一个double型数据：”）；a= int (a*100+0.5)/100 ；printf("%lf",a)。} 这时候printf输出的结果将是5.14。

Fusion of the single-stranded DNA (ssDNA) cytosine deaminase APOBEC to catalytically inactive or nickase variants of Cas9 led to the development of the first precision base editor capable of introducing single nucleotide substitutions (C•G-to-T•A) in vivo10. This breakthrough technology ...
