C語(yǔ)言中的數(shù)學(xué)函數(shù)是進(jìn)行數(shù)學(xué)計(jì)算必不可少的工具，在程序中經(jīng)常用到。本文將介紹C語(yǔ)言中常用的數(shù)學(xué)函數(shù)，包括數(shù)值運(yùn)算、三角函數(shù)、指數(shù)函數(shù)、對(duì)數(shù)函數(shù)、取整函數(shù)等，讓你輕松掌握數(shù)學(xué)計(jì)算。

一、數(shù)值運(yùn)算函數(shù)

1. abs函數(shù)求值

tt x);

2. fabs函數(shù)求浮點(diǎn)數(shù)的值

double fabs(double x);

3. sqrt函數(shù)求平方根

double sqrt(double x);

4. pow函數(shù)求冪次方

double pow(double x, double y);

od函數(shù)求浮點(diǎn)數(shù)的余數(shù)

od(double x, double y);

二、三角函數(shù)

函數(shù)求正弦值

(double x);

2. cos函數(shù)求余弦值

double cos(double x);

函數(shù)求正切值

(double x);

函數(shù)求反正弦值

(double x);

5. acos函數(shù)求反余弦值

double acos(double x);

函數(shù)求反正切值

(double x);

三、指數(shù)函數(shù)

1. exp函數(shù)求自然指數(shù)

double exp(double x);

2. log函數(shù)求自然對(duì)數(shù)

double log(double x);

3. log10函數(shù)求以10為底的對(duì)數(shù)

double log10(double x);

四、取整函數(shù)

1. ceil函數(shù)向上取整

double ceil(double x);

2. floor函數(shù)向下取整

double floor(double x);

d函數(shù)四舍五入

d(double x);
